It's all about stress management. I'm of the opinion that stress is the worst part of any process like this. If you start to overthink things, they begin to consume your life, making you sleep worse, making you feel worse, really making you unhealthier. And worst of all, we put all of this stress on ourselves.
All I did was make a list of everything I needed to do at the beginning of this process. Every couple of days, I would take one item on my list, and work for maybe 15 minutes to an hour. Then I would go out with friends or do something fun the rest of the night.
Yeah, there are a lot of elements and variables to the application process, a lot of things out of our control (slow professors on LoRs, I was pretty worried around Dec 1), but the worst part is what we do to ourselves.
The more we include destressing activities in our day (different for everyone, could be exercising, weed, watching tv, anything really), the easier the process becomes.
But that's just my attitude, and who knows if I'll get in to my programs. But I'm still confident, and that's probably because I never let the stress get the best of me. To be honest applying to college was a lot more work than this.
