Feeling sooo sick

I was diagnosed with fibro 3 years ago & was started by my rheumatologist on Cymbalta. It helped a lot for the first couple of years, but then I got all the side effects of the medication. After trying different remedies prescribed by my rheum. and primary care, I almost weaned off the Cymbalta which, in my opinion, is a horrible drug. Meanwhile, the lower the dosage, my fibromyalgia symptoms are all coming back in full force - the pain, the exhaustion, the depression, the tingling, you name it. I want to stay in bed all day. I'm told water exercise is good, but I can't even get myself down to my apt. pool. I am 79 years old and feeling soo sick & hopeless. Today, I am very nauseous. Can someone help me suggestions?
