At this point I'm going through my statement of purpose. I have my writing sample. I have contacted all professors who have committed to writing recommendations -- they've all gotten back to me. I've contacted an historian who I did research for and she's also assured me she'll write me a recommendation. I've also got my GRE test date set up. Planning on acing the verbal and writing, yet super annoyed about the thought of doing math for the first time in over 6 years.
Right now I'm shooting off my emails to professors to see if they're available in the Fall 2013 semester.
Honestly, what's getting me through this is just sucking it up, applying to schools regardless of that nagging voice in the back of my mind telling me I'm "not good enough," and talking to friends who have already gone through this process.
