I accepted a spot to a PhD program at my undergrad institution. However, I made the decision for my significant other and not for myself. I wanted to go to school B. I thought if I made the decision to go to my undergrad school, I would learn to be okay with it. That is not the case, unfortunately. I can't help but think that I have made the biggest mistake of my life. I do not feel excited about attending the school at all. I want to rescind my acceptance and go to school B. The problem is, I know this is very bad form, and even more importantly, my best letter writer helped me get into the program at my undergrad school so I may possibly burn all my bridges with him if I decide to rescind my acceptance. Any advice? Has anyone been in a similar situation and regretted their decision?
