I'm currently in my first semester of a physics PhD program, straight out of undergrad. At the end of my senior year of undergrad, I was already feeling burnt out and tired of course work, but my profs pushed grad school as the smart and best choice. So I went. Since I moved here (14 hours from home), I haven't been happy. I haven't been able to make friends with my cohort, even though I've been trying. I haven't been able to find any motivation to do my homework, and I don't like my classes. Although I was studious and disciplined as an undergrad, I haven't been able to get things done here, and I've started having episodes of depression coupled with bad homesickness. (I just recently started seeing a counselor.) I'm starting to think that maybe I'm just not ready for the demands of grad school. I realize everyone has problems in grad school, but I can't seem to get my act together. I think that I would do better if I took some time off to teach or do part-time research. Would it be acceptable for me to quit after this semester or the next? I don't want to waste the department's time and funding if things are so bad, but I don't want to be that person who quit after one semester.
