Re: I don't know if it is depression or not.
One of my friends was like that as well during her first year of college. She was very homesick. She was getting very stressed and moody very easily and actually tried out some anti-depressants and they really helped her. I would also sugggest talking to a counselor at your school. At my university, counseling is free since it's included in tuition. I also did the same and it was great to be able to talk to somebody about it who I know I could trust. At first it was kind of weird but I got used to it pretty quickly since the counselor was very nice. I also tried anti-depressants after talking to her about it for a while. The one I tried wasn't for me, but I may consider another soon! Some people get depressed from things happening and some people don't have a good reason or at least don't KNOW why they are depressed. Some days I have no idea why I feel so down! It's different for everyone.
