Thanks to all of you for the support and kind words of understanding. Yesterday, I *finally* received my first full acceptance letter (whew!). And whether or not I decide to go to that school, the acceptance, at the very least, validated my efforts. I'm also waitlisted at another school, with hopes of getting in. At this point, I feel uber fortunate to have gotten in anywhere.
So many of you have pointed out (and rightly so) that this year has been especially rough on grad students. It's crappy and it doesn't seem fair that so many talented, viable candidates are being shut out of programs as a result of the economy and job markets. I just hope that by the time we are all done with out PhD's that we will emerge to a better job market.
Again, I really appreciate the time all of you took talking me off the narrow ledge of despair. Best of luck to all!
