I Get Akathisia About 3 Days After Taking ANY Antidepressant.

I get akathisia about 3 days after taking ANY antidepressant. I also get it when I take Klonopin, gabapentin, etc. I have tried roughly 8 anti-depressants, anti-convultants, etc. I thought I would try some vitamin supplements, Vitamin B complex & D 3, a few days after taking these, I also developed akathisia. What may be wrong with my body/brain to be causing this with anything I take? I need help with my depression and anxiety but have been unable to get any help because everything causes akathisia. Help?
