i have fibromyalgia, too (i was linked to your lj by a friend) and wanted to put something on this to make you feel less alone. we all suffer from feeling lazy or "just depressed," at least sometimes, but its not that simple.

fibro is going to keep being frustrating, but there's support online- so you can get information and community if you want it to be there.
