Thank you so very much for the words of encouragement, everyone! I love this community and you all really are so, so sweet and kind.
I cried in the bathroom for a while but then went out for a short run. I feel quite a bit better already! I'm really hoping having a four-day weekend helps me recharge and recuperate.
In retrospect, I think I probably should have waited another year before applying. I suspect that I was dangerously close to burnout towards the end of undergrad. Last VMCAS cycle was kind of a "test run" as I sincerely believed that there was virtually zero chance of me being admitted anywhere with my crummy GPA--lo and behold, I recieved no rejections. I never could have imagined this happening. I mean, I was the girl who attempted suicide her senior year of high school because I was close to failing out and not recieving a diploma; I thought I had no future (obviously now I see that there are alternative routes, but 18-year-olds aren't usually the most forward-thinking). I thought that there was no way I could ever get into college or find a halfway decent job... and now I'm in vet school! Craziness.
I guess I just have to remind myself that of the 1000ish applications my school recieved, and the 350ish interviewed, I somehow managed to stand out and that I am here because the school truly believes that I CAN make it.
I am happy--and grateful--to be here. That's why my feeling the way that I do frustrates me so much.
