Over-medicated?

I have recently opened my eyes to the huge possibility that I am being greatly over-medicated by my psychiatrist. There are many reasons for this. Many different “symptoms” started popping up over the past year and a half. He has been my psychiatrist for 9 years. I recently have been studying the medications that I have been prescribed. Things for epilepsy, Parkinson’s, seizures, schizophrenia, bipolar, and much more. None of which even he has ever diagnosed me with. I have MDD, GAD, PTSD, some OCD very much controlled. Also TD, from an incorrect drug for my diagnoses as well. I certainly have nothing against folks who have all of those illnesses, but I would like to be treated for what I do have. I’m extremely hurt, and feel very alone in this area right now. I have dealt with my actual diagnoses for 40 years. I was 22 when it began. Because of my husband’s job, we moved a lot, so I’ve had several psychiatrists over the years. I have never been on this many drugs, or felt so crummy in mind and body. All of my teeth need to be removed this week, because of the horrible dry mouth from a drug that my current psychiatrist does not remember why he put me on it. The current dentist I have said that she can tell that I brush and take care of my teeth, because my gums are perfectly fine. Each day more roots of my teeth are showing. There is really nothing that can be done, but me now having to wear dentures.
I’m not sure where to go from here. I’m wondering if any of you have gone through something like this, and what you did about it. I really liked this doctor. He was so nice. Now I’m so hurt. I’m in a state of shock. I don’t understand what he was doing at all. Every time I had a rough or rotten day, I was given another drug. I feel so dumb that I didn’t get it. But my brain has been fuzzy. No wonder.
