I wish someone knew the answer. I don't take as many showers as I should either. It's not the feel of the the water or the sound, it's just overwhelming, wash my hair, shave my legs, etc. I usually shower once to twice a week, wash up in between if I'm going somewhere and wash my hair 3 or more times a week if im going out. I always feel better after I shower but it's overwhelming to actually get in the shower. Even when I'm manic im the same way but when I'm in a deep depression I couldn't care less.

If I actually tracked it's probably less. My husband is disabled with PTSD and he is the same way although I've never asked him why.
