If your college has a counselor, I would encourage you to talk with them, or someone in the health/nursing office. (or a friend/family member). It does sound as though you are depressed but you also have skills and time--- (I found my 20's very difficult...)---
Check out articles here on PC on depression and related subjects & do keep going through the motions (is that how it feels?) of doing your usual activities. Could you use your art to explore your feelings?
