I'm so glad i'm not the only one...same as you all have said, my professors, student colleagues, and parents all think I will get into at least 4/5 I applied to (one is a "reach" school for mostly everyone, imo). I originally felt like my only huge downfall was my GRE, but after doing more research on the types of candidates my schools accept and their average GRE/GPA/experience/etc., I think i'll be lucky to get into one. I wish I would have realized that I needed to set more reasonable goals for myself long before the many hours and many dollars spent on applications.
It will mostly just be embarrassing to the aforementioned people if I don't get in anywhere, really.
