What do you do with constant and I mean constant pain??

I wasn`t sure that I was going to make it to my 58th birthday, today. I`m trying to help my mother (84) take care of her house and property. My father passed away almost 2 years ago. I am suffering from fibromyalgia and sever athritis, runs in the family. Some days I hurt so bad I can`t move, at all... But I`ve lost 90 lbs.. I`m the same wieght that I was when I got out of highschool in 1969, my doctor has already done every test there is on me and I`m ok, sort of( hypertension and a stint in the hospital with a blood clot in my left lung, almost killed me).

 But I`m in so much pain every day that some times I think the best way to deal with it would be to take a walk in the woods and not come back! I can`t take NSAIDs because they make my guts bleed, I only have one option, opiods, and they suck, but work, sort of...
