Im exhausted, the pain is too much. I keep trying to find

Im exhausted, the pain is too much. I keep trying to find a way to get through one more day, but I am running out of hope & medication options. I don't think the remicade infusions are helping. The Dr told me it would take 3 months of treatment for it to work, Monday will be 3 months. Im still in bed on pain meds. I still only get 2 or 3 days a month when I can get dressed & leave the house. I've failed on 3 meds since September. Maybe the Dr is wrong, maybe it isn't seronegative spondyloarthropy/ankylosing spondylitis. Maybe the pain is neurological, or the chronic fatigue syndrome & fibromyalgia are constantly flaring up. I don't know what to do. Everytime I get a new diagnosis, new medication, surgery, physical therapy, counselling, pain management clinic I try so hard. I do everything I am told to do. Im positive, I have hope & then nothing gets better. Im 46 years old. I've been in pain since 1996. I can't be disappointed again. I don't want more Drs, more treatment options. I can't do it anymore. Its been 12 years maybe its time to just accept the pain & the life its taken from me.
