I find that if I don't shower at least every other day, that I notice it and that makes me feel even worse. So when I'm really struggling I will strip wash to get the minimum done. Also my hair looks awful if I don't wash it most days. I can totally relate to the lack of motivation though to self-care though. I have trouble looking after my teeth too, even though I worry too about the consequences. I think that this lack of motivation could really be the meds.
