Do you have a T? It might be interesting to ask him/her about it. I would say that if you dissociate and are easily distracted that you might ask that testing occur outside of the class in a 1-1 setting. The academic support center should help. Also, depression, it would be great to have someone who acts as a coach and helps you schedule tasks in managable bites so you don't get overwhelmed and you have a plan to not procrastinate. Speak with your school and see. The pain in the butt is that I believe they all want documentation and that might feel weird to share your personal medical files.
