Hello wllwrt4fd and welcome back.
Ok; let's do a process of elimination scenario here.
You saw doctors and psychologists.
Was the doctor an actual neurologist?
Did they have MRI's and/or CAT scans ordered?
Excessive amounts of stress have been known to make bad situations feel worse;both physically and psychologically.
Have you had a complete physical(including blood work) to rule out any deficiencies?
I've just began to scratch the surface and can definitely relate to your plight.
