My daughter was put on an antipsychotic drug that caused her to commit suicide can I sue the doctor???

My daughter went from being and anxious smart young woman who just graduated university then started seeing a psychiatrist for her anxiety and he put her on this horrible drug resperidone and I saw her change and go down hill until she didn't want to LIVE! She tried to get off of the drug. Her insurance changed to medicaid and the dr. dragged his feet getting coverage. He said he could not treat her for free. This idiot left her in this state. She was anxious about paying the bill and should have been under his care still. He still prescribed the drug and was not seeing her and she killed herself. Never wanted to do this before EVER! This was the wrong DRUG. She was not schizophrenic and he put her on a drug for that.
