Hi,
Sorry to hear about your accident and concussion.
I know it's hard to accept. It won't always be this way. You can improve.
Hubby had a concussion and a stroke and had a C1 burst 4th of July. He has a lot of vision disturbances. We found neuro visual rehab therapist. Just getting started with that therapy. Didn't know it existed before his need for it. This is 1 1/2 hour one way, in Ashland, Ky, twice a week.
Google around for one in your area. Very promising.
I do understand. You are not alone here.
Ky also has vocational rehabilitation services that you might find helpful, for retraining skills. It's a government program.
Take it easy. Give your body time to heal.
Lots of friendly people here that have been through it. Lots of info here.
Hang in there.
