I have mixed connective tissue dissease and chronic fatigue and fibromyalgia my doctor has pretty much giving up and u please suggest some medicines.

Try no medicine: And instead walking in the sun with a friend. Start slow and increase a little each day, while you look for a different doctor. If you have run through a 1/2 dozen doctors without relief, use you time and money to change climates rather than another doctor. If you have not seen a rheumatologist, a chiropractor or an interventional pain management doctor, you should consider it.

Second opinion: These are pretty straight forward issues for a rheumatologist. The diagnoses need to be confirmed, past treatment reviewed and then options can be identified - dependent upon what each is causing.
