Talk to Rheumatologist on Fibromyalgia

Diagnosed with Fibromyalgia. Firstly it was misdiagnosed as GAD and I was prescribed 20 mg of Duloxetine (cymbalta). But then the dosage would stop numbing pain for a specific period of time so my psychiatrist would up the dosage and this way I ended up taking 30mg for initial 4 months then 60 mg for 4 months. Been total 8 months taking Duloxetine. But then 60mg also stopped working and pains came back. I decided not to take 90mg instead started tapering it off by dropping 10mg after every 2wks. I felt no withdrawal symptoms and pain was manageable until I was on 40mg but now I am back to the bad bad condition that I had 8 months therapy doesnt work psychotherapy every week so that my withdrawal symptoms and moods remain manageable. But the main issue is this pain. What do I do to at least lessen it? 2 years ago traumatic event caused my fibromyalgia. My studies and daily life is being badly affected due to this pain. What do I do? I am already trying my best
