I am in the same boat with you -- the spacy head thing is the WORST since I feel like I am losing my personality, that along with the fatigue is killing me. Sigh . . . I was so hopeful of being better right now. I really think the progesterone cream screwed me up. Very worried that something else is going on, and am going to go in for another hormone/thyroid/adrenal function panel soon, and am thinking of getting tested for Lyme, worried about CFS.
I think that 90% of me is overreacting at this point, and I just need to give it time.
Other women have made it throught this and I am SURE that we will, I just wish it wasn't so hard and didn't take so long.
