I just wanted to say thanks to everyone for your replies! I really appreciate your detailed answers.

This last semester, I actually did go to my college's counseling center. I was planning on continuing this summer, but my schedule doesn't really have time for it. I am currently trying to decide if I want to go back next semester. I don't really know if it helped me or not. It feels like I have (or am acknowledging) more problems than before, but I haven't found any solutions! It was kind of nice having someone to talk to, but it was a little stressful to go and I don't feel like I made much progress.

I might stick with self-help for now, if nothing changes between now and then, so let me just say thanks again for helping me to try and figure out my head!
