It sounds like you need to talk to a doctor about getting started on an antidepressant/anti-anxiety med. You do not want to start one when away at school.

Have you been using a antihistamine to help with your allergies? It should help dry up your ears.

Have you talked with your colleges health service to see if they can help you prepare for school?

Are you going away to college or staying home and attending a local school?

What kind of activities do you do in an average week? How much sleep are you getting? What kind of stress is there at home? How is your diet?

I don't think you are close to taking on a normal schedule and lifestyle. Your brain still needs more quiet rest and you need to get control of your anxiety and hypochondria.

If it helps, I believe the best concussion neurologist on the east coast in Dr Robert Cantu in Concord Mass.
