I'm just going to throw in my 2 cents here. You may feel very alone and different, but I'm guessing that in every class you attend, in your dorm, every where you go, there are a few other people who feel the same (or similar). You are not alone.

I've been there. I've always felt I could handle it myself, figure it out, but over time I gave up on it. I now, in my 50's, am in therapy. I wish I had done it when I was much younger.

Reach out to the counseling service on the campus, that's what they are there for. Play with some different things to do unrelated to class work. Explore, maybe slowly at first, but do explore. And give yourself some time to adjust too. Most importantly, don't worry about what you want to do right now. Concentrate on your gen ed requirements. In time it will come to you.

Best of luck and hang in there.
