You are being treated for conversion disorder
(with what medication?). You experience symptoms - twisting of body and involuntary movements
. You say people do not believe you, you haven't specified family? friends? doctors?
There can be two reasons for this problem. One is side effects of medications. Another is a symptom of your illness itself considering you are a case of conversion disorder (you have not mentioned the symptoms). Either ways the next step should be to visit your psychiatrist
Hope this helps,
