it doesnt sound like a serious psychiatric condition that needs psychiatric evaluation. more like just being overstressed, that's all. everyone's stressed.

plus u're a student, shouldnt have that much of stress unless broken family, failed all exams, etc.

sometimes we tend to self-diagnose cos we want to think that there is something wrong with us, so that we can put the blame on something.

i can see that you are having symptoms of mild depression to some extent, but not severe enough to warrant treatment by psychiatrist or receiving anti-depressant medications. perhaps a counselor, or a psychologist, would be able to help.
