Feeling at my wits end with Chronic Pain and Fibromyalgia

Usually I am not one to share much of my personal story but here goes...I have what is called moderate to severe degenerative disc disease, arthritis of the spine C3-C7 and lumbar spine, and Fibromyalgia. In the 20 years Ive had pain, I"ve been though many treatments including PT, tens unit, bio feedback,injections, nerve ablations, you name it. I'm prescribed Cymbalta 60 mg for Fibro and anxiety as well as 225 mg of Lyrica. I have been on and off various painkillers too. I'm currently on a long acting oxycodone of 13.5 mg and once a day one 15 mg of IR oxycodone. This has been my regime for a few months now as I switched from 15 mg IR oxycodone. Now for those who are worried about me ODing...I understand. I actually hype-vigilant about my meds. (And I have my hubby and son who watch) Years ago I was on 15 mg Fentanyl patch for 10 months and came off it in one month with no side effects.
Right now I'm really struggling with this rotten pain. I have no appetite, either can't sleep or nap during the day.
