I Have Been Having Problems For A Year Getting Out

I have been having problems for a year getting out of bed, falling, dizziness and not being able to walk properly. My neurologist said it was Parkinson's butt it was probably due to my bi-polar medication. I take thorazine, zyprexa, lamtrogine, valyar, ambiem and clonazampam. The most recent medication the Psychiatrist me on was Vraylar. Which would you suggest for my doctor to start decreasing first? I have been hearing voices for a month now.
