Hi there! By all means talk to your school counselor or nurse about this. College is wayyyy different from high school and the way you've gotten by thus far is unlikely to carry you through postsecondary education. It will definitely give you problems in the working world (voice of experience here!). So yeah, sure, see what you could do.

There are lots of ways to help ADD, not just medications. You may well find other things that work for you.
