Holy mackerel, seeing this thread makes me feel so much less alone, and this is a pretty old thread! Of course, I'm also sorry everyone is having such a hard time with this. I have the same problem getting myself to shower and brush my teeth, especially when depressed. I don't understand it either, because I love how I feel after the shower, but before I actually shower, I always feel like washing my hair and everything is such a task that's going to take forever, so it just turns into this daunting thing that I dread. I go as long as I can without showering, usually a few days between, washing my hair once, maybe twice, a week, if I'm feeling particularly energetic. I'll shower if I know I "have" to—some special occasion, doctor's appointment, etc. but day to day, I'm usually trying to convince myself why I don't need to shower tonight. It's also weird because I am so grossed out by germs in public places and things being generally dirty. It's just so difficult! It makes no sense!
