I don't mind showering, but it is a lot of work. I go through cycles that may or may not coincide with my depression. When I'm more depressed, good luck getting me to muster the energy for a shower (longest I've gone is maybe a week and a half without). When I'm in a better mood, I shower regularly unless I am struggling with my si (one of my preferred places to si). The most I've ever showered was twice in one day because I got really gross and sweaty, or dirty doing housework, or have been to the beach and need to wash the salt water off.
I have body image issues, but I also generally feel really detatched from my reflection (and for whatever reason I don't see my body as a whole when I'm in the shower, just parts that need to get cleaned up), so seeing myself in the mirror is more of a fascination thing; "that's what I look like... ok..."
weird... I know...
