Next time you see a doctor, Try this:

I suffered a severe concussion last year with a brain bleed. I understand there is no quick fix or magic pill but I am struggling with my symptoms. I am looking for someone who can help me manage my symptoms. Can you help me? Or do you know someone or some place that can?

Rehearse this. Doctors want to be appreciated and like to know they have a direction to try to take their patient.

I wonder if you could be seen at the University of Nevada School of Medicine Clinic in Vegas to begin a study with some med-students/interns. I don't know if this is available but worth asking. Too bad the School of medicine is in Reno. That would be a worthwhile place to try. Teaching hospitals sometimes can assign a group of interns to work with you on a longer term.
