I'm sorry to hear you're having so much trouble. I have had CFS/FM for 35 years and also have a considerable amount of pain and fatigue. I don't think it has anything to do with giving up or not trying hard enough however.
For me, both of these illnesses have been progressive. Now, I also have several other conditions to deal with. My sleep cycle is reversed and that adds to the problems.
I feel that if I can make it through each day I'm doing okay. I just do the best I can and try not to let discouragement get the best of me. Sometime it works, sometimes it doesn't. :)
I wish you the best and just wanted you to know that you're not alone in this struggle. I also sleep 12 hours and am up for about 8. Then take a 3 or 4 hour nap.
