Honey I think basically everyone on this board knows exactly what you're feeling! It's so hard to put yourself out on the line like that and say: "Okay, here is my all. This is the best I could give you. Now you know my personal and academic history, my dreams and my goals. And here's $80 so you can decide whether I'm worthy or not."
Basically, it sucks.
Read enough threads, and you'll see all sorts of whacky stuff. People stalking their postmen, others drinking heavily, people with nighmares ... I once dreamt that I was reading over an application I sent and found a HUGE typo in my PS. I should NOT be having dreams like that!
Anyway, you will NOT get rejected from all your schools! But the waiting part is really craptastic. Just awful. Some people have been waiting on schools since October. Hopefully for you, your cycle will be over quickly.
Best of luck!
