i relate to pretty much everything you said. life is a lie, sensory experiences, rotting, feeling muted, seeing faces in everything.

sometimes what happens to me if im in a really bad episode, my mind splits (i dont think i have DID). i can sometimes bring out this personality if i need it but sometimes i cant. anyway, my mind splits into 2 parts. one is how i currently feel where i cant cope. then the other me is comforting and says things like " you can do it" and i can take care of myself this way. like when i shower it says "now get the shampoo" and stuff. it helps in times of trouble and i ffeel like im not alone.
