Going to college was the best thing I could have done for my OCD. For one, if your university is anything like mine, there will be a lot of resources for people with mental illnesses. We actually have a full medical clinic on campus, and the whole top floor is dedicated to psychological stuff with a staff of therapists. I'd look into whichever college you chose to go to and see if they have something similar. Also, you'll meet a ton if new people, and if your experience is anything like mine was, like attracts like. You might find that a lot of your new friends have psych issues as well, and it's a LOT easier to go through stuff as a team.

As for schoolwork, when my symptoms were at their worst, it was a little challenging to get things done. Aside from getting therapy and the usual advice, try working in a public place, like a library or student union-type place or study area. I've found it's a lot easier to resist carrying out compulsions in a setting where other people are around (my symptoms tend to be worse at home or at my dorm). That's just me though -- something else might work better for you. Best of luck! (:
