Hey all, I've read this forum frequently through my grad school application process, and it has been full of helpful tidbits. Now I have an odd situation of my own that I would appreciate feedback on. I applied to a bunch of PhD programs last fall. I hoped to get into at least one, but I honestly felt like there was a real possibility that I'd be shut out from all of them. Now, a few months later, I have multiple fully funded offers, several of which are at top ranked schools. I should be feeling over the moon, but I'm not. I mean, I was proud to be accepted at the time, but I'm so worried I'm going to pick the wrong school or not live up to everyone's expectations. The prospect of picking a program is really tough. I am excited about my field, but I really torn between programs. It also is terrifying to think I could end up living in a new city by myself. The transition seems very difficult. Also, I am in my last semester of undergrad right now and am genuinely struggling with a class. It's a 100 level class, but the professor is an extremely difficult grader. Every other semester, I have gotten straight As. My other courses are difficult as well. I am worried that if I do poorly in this course, I might have my offer rescinded. It would be easy to read a B or C in a 100 level class as senioritis/laziness, especially when coupled with a B elsewhere. I am working just as hard as I have in previous semesters... it's just by chance that I ended up with several tough professors this semester. It also doesn't help that I have missed so much school for interviews! I have considered doing a pass/fail option on the difficult 100 level course, but I'm not sure if that would be read even worse. Most of my acceptances were conditional upon completing undergrad, but I advertised in my application that I will have finished this 100 level course by the time I begin, which is obliquely related to the field. So, my questions are: --Am I crazy for not being happier? --What can I do to be less worried? --What's the likelihood that an offer will be rescinded? Basically, I feel like the world has handed me a tremendous opportunity and I feel insanely guilty about not being more excited. Thanks in advance.
