Suffering from fibromyalgia. I can do!

Hi, It's been 15 years since my symptoms initially appeared, first cervical pain, then back pain and every year a new pain gets added. I have medication resistant pain, or they don't work now properly as they gave me more pain so i have to change pain medication every other day. Recently from one year have developed digestive issues, so the medicines are even more of a hit and miss now. I have taken ketamine and lidocaine treatment also. Needless to say nothing worked. With all these things i have also the usual suspects- anxiety, depression, bpd. I have changed doctors so many times and i think no one beleives me and now recently last doctor thinks i have drug seeking behaviour. Well offcourse i do, i want to be in less pain. I know i should do the usual things - exercise etc but i consider enough achievement to get to work every day. So what is something that i can do
