Kelly,

12 units may be a light load for a normal full time student but it is likely too much for your concussed brain. Have you done any serious though about your triggers. The physics lab probably had lots of sounds to over-stimulate.

Try wearing ear plugs during class. It may help.

Your soccer history was likely full of sub-concussive impacts leavening your brain in a very sensitive state. Add some tears to the damage and you end up with a brain that will struggle to recover from a concussion.

I would not put too many expectations on the visit with the neuro except to rule out other issues.

I doubt you will break anything. But, you can continue to exacerbate your symptoms such that you end up on a long roller coaster ride.

I understand you struggles same difficulties in college except I did not have the panic attacks.

btw, Have you tried propanolol to lower your blood pressure when you suffer a panic attack. I keep some in the cabinet to help me recover from those extreme panic attacks even though I am on a maximum dose medication.

My best to you.
