I can't advise you or second guess your doctor because I don't know enough about you. Usually when there are this many medications, I like to ask for a comprehensive review by a specialist. If your doctor is not a psychiatrist or a psychopharmacolgoist, I would ask him or her for a referral to one of these specialists.
Keep in mind that none of the medications is a CURE and will only give symtomatic relief.
You will eventually have to seek the source of your pain and forget the pain,find the source!.
good health
