Hi Jenn, Personally , I think your dr should check you for other things first. Like the diabetes. He should do a complete blood count (CBC). Rule out other things first.
My fibro symptoms started at 24 yrs old (or was it 23???

). After birth of second son. I'm 35 now...and the fatigue still is my biggest complaint. It just knocks me right off my feet.
I've just recently been experiencing hip pain on both sides. I too have endometriosis.
We have 2 boys, and I know what you mean by feeling guilty for not having the energy to be more involved.
That just gets ya right in the heart!!
Let us know what the dr says, ok? Get some other things tested and ruled out first.
