Could this be Fibro?

For as long as I can remember I have hurt, everywhere, ALL the time. I have been tested for all types of arthritis and they have all come back negative. Many doctors have suggested I may have Fibromyalgia or some other sort of auto-immune disorder. I don't take anything for the pain anymore. I "used to it" sort of. But I do wish I could get rid of it. Some days are worse than others. But my symptoms are (and some may be related to the conditions listed in my signature):

Insomnia
Constant pain
Pain flair ups in random places
Waking up sore as if I just had an extreme workout
Lack of focus
Occasionally blurred vision
Slurring in the mornings and evenings
Extreme thirst
Either extremely hungry or cannot eat
Sleepiness during the day
Random weird cravings
PAIN

I have tried all of those except for meditation.. and they only temporarily help. Acupuncture helped most but I can no longer afford it.
