Hallucinating...help?

I've had Chronic Daily Headaches for 5 1/2 years, for four of those years I've had hallucinations. I've been hospitalized many times and the headaches have remained undiagnosed. Along with the hallucinations, I've fainted, dizzy, no appetite etc. They've found nothing. I'm just concerned because the headaches are getting worse, so consequently, so are the hallucinations. And people are starting to worry. Am I overreacting, or should I see my Neurologist?
