Most of my crashes are total pain and fatigue, just unable to move or do because I hurt so bad and cannot stand it. The past few months though, every couple of weeks I have a total "burndown" where I feel as though my entire body has shut down on me. I cannot move, walk, talk, think or anything. I HAVE to sleep, and nothing else will do. It is a time of just "being", and barely that. My mind doesn't comprehend what's going on around me even. There are no emotional feelings in me - I just "am". If I do get up, I am sooo off balance I cannot walk without running into everything, and cannot even stand upright. I will sleep anywhere from 20-28 hours and then feel groggy, but better. My husband simply doesn't understand this part of the whole disease, how one day I am "okay (in pain)" and the next nonexistant. Does anyone else go through these episodes? It's too much for me to understand.
