Hey, I defintely feel you on this one. I cried when I got my first rejection, and it wasn't even a school that was on the top of my list--it just sucked that it was the first news I got. Feel good that you have had interviews at least, I'm still waiting for ONE school to decide they might actually want to meet me.
This process is so hard, I thought studying all summer for the MCAT while working full-time was difficult, then writing all the essays and spending all the $$ on secondaries--but this waiting is actually much worse. You think once you've cleared the hurdles and gotten a decent MCAT score and turned in all your secondaries, the hard part is over, and it's just a matter of getting interviews and hopefully at least one acceptance after all that...ha! Each day that goes by without any news, I feel more depressed and hopeless. It doesn't help that coworkers, friends, family, etc. keep asking every day, "have you heard anything yet?" and I get to keep telling them no, looking and feeling like more and more of a loser.
