I recommend that you change your profile on this BB so that your current institution is unknown and it's less difficult for someone who knows your field(s) to figure out the identity of your current advisor.
I suggest that you find ways that you can evaluate your current program and department more on its own terms and less on your expectations and/or the experiences of your mentors. The re-evaluation may provide a different perspective that will help you as a graduate student there or elsewhere. (Specifically, how to manage differently your expectations of faculty members.)
I urge you to consider a path in which you make a best faith effort to adjust to your current program. If things don't improve, get a master's degree where you are and "transfer." You'll have a better story to tell if you make the transition after earning a masters as opposed to withdrawing now and starting from scratch. 
In the event you decide to transition now, I recommend that you exercise great care in disclosing details of your personal life to POIs and/or the "dirty laundry" of your current program. All things being equal, there's a significant chance that professional academics will conclude that you might be a disruptive presence that they don't want to deal with.

I'm interested in this too -- one of my options is staying at my undergrad institution for an MA and reapplying in two years' time (and my choice might be determined by finances). I've heard that in my fields (linguistics, medieval studies) that it looks kinda bad to job hiring committees if you stay for your whole PhD, but I'm not sure if there's something similarly negative about an MA to admissions committees for PhD programs.
And maybe it makes a difference what you do during your master's if you stay? If you really apply yourself to come out with top marks, conference presentations, maybe publishing, get in on conference/workshop planning, etc -- perhaps that would overcome any potential trepidation that you just cruised into a master's as essentially an extra year of undergrad?? I don't know, so I'm looking forward to hearing what others have to say! 

Staying for your MS/MA isn't a big deal. A lot of people do. There's also many programs that gave combined BA/MA programs where students earn both simultaneously. You don't know want to stay for your PhD though. 

I'm not yet a graduate student, so I can't say for sure, but there are several factors that will influence making friends that are different from undergrad!
For one, are you going to a state school or a private school? The culture of the university is usually the main attraction for undergrads and not graduate students (who tend to gravitate toward research potential) but if you're surrounded by parties, party-minded graduate students may go out and drink and dance as well. If your university is in a place with no bars then "parties" may be more get-together like, with some light drinks and board games.
Next, is your university graduate only or do you share the campus with undergraduates? I'm going to be attending CUNY, which has an entirely separate campus for graduate student classes, so the only undergraduates I will talk to will be in the labs I rotate in. Most of my interaction will be with my graduate cohort and not undergraduate students.
Third, the ages of graduate students vary greatly, especially when you factor in international students. The graduate student I'm interning under in my post-bac position is Korean, and she is almost 30 years old and in her third year. My PI is also Korean and he said that the norm is for Korean students to wait until around that age to begin graduate studies. One person I interviewed with at CUNY will be graduating undergrad at the end of this semester and told me that she's 21. I'm 23 myself, having attended undergrad for 5.5 years. So your desire to hang with "older students" might not work out so well, despite your graduate status.
Lastly, do you expect to only make friends within your cohort or will you also be attempting to make friends in the city/town you live in? If you like D&D or hiking or some other hobby you can easily find meet-up groups to make friends without drinking/bars! I already have a ton of friends in New York City, and they are all professionals, so I'm not depending so much on hanging out with my cohort. Of course I want to be friendly with them but I don't plan to stick around them in all of my free time.
Hopefully this helps, even coming from someone who just got their bachelors ?

I think this will vary a lot as not all grad students are right out of undergrad or even 20somethings.  A grad student with kids and/or a spouse will have a different experience making friends compared to those who don't for example.  I think it really helps to not limit yourself to the students in your department or even your university when it comes to making friends.  Establish hobbies off campus, go study in cafes in different neighborhoods, go to random events all over town, join meetup groups, etc.  If you don't want to work all weekend then make your work week so productive you don't need to.  If drinking isn't your thing, find other activities to enjoy.  My weekends only involve work if I should to play hooky on a weekday or if I feel crazy inspired.  Otherwise my weekends are for self care, socializing, or just lazing about.

In a vacuum, staying at your UG for an MA/MS is no big deal. But your case is a little different. You applied to other schools, did not receive attractive offers, and stayed at you UG for an MA/MS. What can two more years (albeit in a Masters program) do to improve your chances. Especially if most of what you are doing is taking more classes? Maybe it can do a lot. I do not know. I just don't the answer is straightforward in your case. 
Moreover, based on your replies in other posts, it sounds like you might benefit from a chance of scenery. I would say work for a year. The ability to hold down a job and do well is not going to looked upon poorly. If it is, the people who do are not worth working for. 

I’d also: 
1. Work on my GRE. It’s stupid, I hate it, I thought my AW score would show that it’s just the multiple-choice formatting of the test that got me down, but I’m guessing not. I shouldn’t be listening to people who told me GRE doesn’t matter...it does. 
2. Contacting POIs ahead of time. This one was huge for me. I should’ve done it but I got so anxious about bothering them or them not wanting to talk to me. I had some great and poor interactions with faculty once I was admitted to universities so I now know that if a professor is annoyed by a prospective student contacting them, that’s a bad sign. 
3. Not completing applications last minute, and not feeling lazy about putting work into them. I fell into a depressive funk my senior year and just didn’t want to do anything at all. Getting out of bed was so hard. But I shouldn’t have let that get in the way of my applications. 
4. Finding a job related to my field. All my jobs are not specifically related to my career field and while they have certainly helped me gain skills that carry over, I need a title on my CV that stands out and catches their eye 
5. Applying to less prestigious programs

hey can you ask your wife to give me some "help" with getting into USC? 
I hear Aunt Becky is familiar with how that all works 

Keep your head up.  If I can serve as anything, allow me to serve as an example (even if not a great one) of perseverance.

Their response is a generic one designed to shoo away all the emails asking for more information.  Clearly, they cannot answer the specific questions of every person who emails them.  So, they do blanket emails.  You can email the POI and see if they can help, but it seems the department is not interested in digging further for you. 
What the content of the email means is that whether you're accepted or rejected, everyone will know by mid March.  My experience with rejection means I'm aware that you're likely rejected and it is safe to be presumed, but some universities don't like to commit to rejecting people until they know they've made all their numbers (of acceptances).  Just contact the POI.  If they can't help you, I would take it as an assumption of rejection (like my signature shows I've done, in this exact situation).

Congratulations, that's amazing!

It was real! Got the official letter today. 

I might be insane but I just wrote a new SOP for next year, assuming I'm not gonna get in this year.  It felt good because I had so many interviews with them and I've been thinking so much about my principles and research goals! I didn't want to write it after I lose the level of focus I have right now. I was SHOCKED how much easier it was to write than the other one. Feeling good about it no matter what happens!

Worries: I am up over my head and drowning with imposter syndrome. I don't think this website is helping when I look at people's profiles and see how much they've accomplished. I feel so...dumb, and average. Like I wasted my time in my three years of undergrad, and I should have done four, or tried in different fields than I worked in so they were more applicable to my application. Being a resident assistant was great because I got my housing and meal plan paid for completely (saving over 10k per YEAR), plus it was good leadership experience, but adcomms don't care about that (unless if I go into Student Affairs). Consequently, worrying that the schools that did accept me are not respected programs that will leave me jobless and possibly in debt. What if I don't get in anywhere else? What if I don't succeed in the places I did get accepted to? What if nowhere offers me funding - that really means I wasn't really accepted...
Excitement: The potential of leaving the state finally. And even if not, I am taking a goddamn roadtrip at some point. I was really hoping that would be across the country to move to California and make stops at all the landmarks along the way. But even if it isn't, I am so excited to be in my car and not tied down to a place for at least a week, just travelling with the windows down and music blasting. I'm already making a playlist and prepping my car. I love driving. Also, excitement of this season being OVER and GRADUATION! Also, the POIs I've spoken to at one of the programs I've been accepted to are REALLY cool, and we're having on-going conversations. If they're actually a decent program and I'm not just succumbing to imposter syndrome, and if they offer me full funding (info on that to come soon, ANOTHER worry...) it could be a really great fit. But it all comes down to funding.

HAHAHA omg, I shouldn’t be laughing but this is the best reaction ever! 

God, I couldn't agree more. I just want to have all my options out on the table, not wonder if a school is just slow to decide or if I'm not worth their time to reject.

I'm in the exact same situation with the Berkeley IEOR program. I know some people have gotten in, but I haven't heard from them since my interview mid-January. I'm not planning on emailing yet because I'm averse to getting bad news (lol) but I think this could mean you're still in the pool! A lot of these larger programs keep huge waiting pools because if a specific candidate with characteristic A and research interest B decides to go somewhere else, they have to fill the spot with someone who has similar characteristics and interests; this instead of a ranked waiting list. 
10-15 is a pretty big number! I wouldn't worry yet. In the meantime, I would suggest celebrating your acceptances. Seems like either way you will have a tough choice to make! Congratulations

It's the 22nd there is not one soul on this blue earth that would say this is still mid-February

"Terrible advice" because it worked for you once at one institution. And since then how successful has your approach to applying to graduate school been?

Just to update, shortly after I posted, I GOT ACCEPTED!
