Your bedrock is sleep. You won't make progress without sleep as the foundation. You also need to work hard on getting a good support group around you. You've got a lot of meds going on. Find a lead practitioner, preferably a concussion clinic to manage your medications. What we found with concussion is you can have 'too many cooks in the kitchen.' Best to find one you trust and stick with their advice and dosing, including supplements. You've got biological and emotional stuff going on, so find a good counselor too.

Hang in there.
