If it were me, I think I'd find a neuro clinic that specializes in some of the less common seizure disorders. That doesn't mean there is no anxiety component to what you experience, but I have a friend with a seizure disorder that went undiagnosed for the longest time because the psych doctors kept going with a psych diagnosis and ignoring the physical aspect until the seizures got so bad they couldn't ignore them anymore.

Don't rely on just any doctor. Find someone with a lot of experience in seizures, because many family practice and internists, even some neurologists, just aren't familiar with the more rare kinds of disorders.
