Hi, Julie! Yes, I think you might be dealing with some depression. However, it could be somewhat situational, since you are not depressed when you go home. I suggest you see about talking to a school counselor about your feelings.

I can also feel depressed, but can act like you act--laugh, dress well, etc.

Adjusting to college can be a major task. Evidently since your depression has followed you, it wasn't just the college you were in that created your unhappiness. Do you really want to be in college at this point in your life? (Just wondering....)
