Not to re-hash a sore subject, but I think it is extremely easy to put all of your self-worth into this one thing that just so happens to be what will determine your future career and ambitions. When you are working on this for years, staying up late studying, sacrificing social and family life, dedicating months to studying for the MCAT, it's hard not to tie this process in with your self worth.
I know I did it. I put every ounce of my emotional investment into the application process, ignored my family, became a combination of a zombie/robot just going through the days without any desire to do the other things I loved. When I saw my doctor towards the end of the latter half of the cycle she diagnosed me with clinical depression.
Some people may have better coping mechanisms in terms of distancing their self worth from their successes in getting into medical school. Others like myself may not. Like gyngyn said, leave the judgment at the door.
On another note, I am still following this thread and rooting for everyone here, whether you are already planning to reapply or still waiting to hear back from schools. Waitlist movement has definitely been slow compared to years past... NYMC and Wake Forest have said their classes are completely full even though historically they pull 1/3 - 1/2 of their students of the WL.
