I've been dealing w/ chronic fatigue due to sleep deprivation (both kids waking and insomnia) and chronic anemia and maybe as yet some undiagnosed disorder and I can tell you it plays havoc w/ concentration and attention. I also had pain for a few months and the pain really just sucks the life out of you. I"m so sorry that such a young person has to deal with this. But I hope a breakthrough is on the horizon now that you have someone who gets it.
