I've been following the current application season and I remember how I felt last year while I was waiting for news from the programs. I was in panic mode. Couldn't sleep, constantly checked my e-mail, constantly checking the results page, eating what I shouldn't eat, drinking more alcohol than usual, etc. In other words, I remember it as hell. But, trust me, I don't regret anything at all. I wouldn't do it again (God, not again!!!), but I think it was completely worth it. I spend several really crappy weeks, but now I'm studying something I love in a wonderful program with wonderful people. So hang in there, keep coming to GradCafe (which helps TONS), and think that, with a little bit of luck, you'll be studying what you really love in a few months.
All my good vibes to all of you. Good luck with your applications and throw a party when you're done, no matter the outcome!
P.S. I leave you with this Chinese parable, which I like and think it's useful during an application process: http://www.cleveland.com/living/index.ssf/2009/02/parable_of_a_chinese_farmer_ho.html
