I have a very severe CFS, almost completly bedridden. Had many tests done and they showed nothing. However sometimes I feel so ill (it's hard to explain) and weak that even talking makes me dizzy from the effort, it's like I don't have one ounce of strength in my body. I usually feel a bit better in a few hours. But I can't stop worrying if I have somithing more serious than CFS. It's just hard to beleive that CFS can make me so ill. It's really scary. Also I often feel so nauseous and disoriented like severly jetlegged and deep bone exhausted. My mum had to support me while walking yesterday when I went to the doctors. Can CFS really make me this ill?
