Cheer up sleepy jean...
I have a pile of rejections and just got a new one yesterday. I didn't think I'd make it, honestly, but by some freak of nature, I did. I've going at it for about two years now. Gave up just about everything I held dear for a shot at medical school. It wasn't looking too good, so I kept moving with the punches. I've cried in frustration and in joy. Now, honestly, speaking from the other side of acceptance, it's worth it, if this is what you want to do.
It's okay to not want to be a doctor right now. I've had that thought pass through me numerous times throughout the process. I just kept on recommitting. You are big enough to want to and not want to be a doctor all at the same time. Take a few breaths, go do something loving for yourself, and let go of what can't be controlled. You are not your acceptances, nor your rejections.
Do you have other interviews, and/or are you waiting on other decisions? I hope so. If not, don't despair. As long as you have the heart for your path, you can regroup, learn from your mistakes, and go at it again.
I think that the worst part of this process is all the intangible, uncontrollable, limbo. The carrot on the stick that seems perpetually elusive. I think this is only the tip of the iceburg.
Anyway, I wish you all the best. Give yourself some space and then ask yourself what you want from a place of ease and flow.
