Hi all. I've been suffering from severe fatigue for a few years now. I've had anxiety and depression for years and take citalopram. The fatigue is what really scares me as I'm convinced it's cancer or something serious... I feel constantly light headed/dizzy/like I'm not in my body. I can't remember anything, even basic instructions and I'm soooo tired ALL THE TIME. Can this really be just anxiety and depression related? X
