For hygienic reasons, I don't necessarily agree with that (I used to get frequent yeast infections - for a reason). But from a cultural/social perspective, it's right. If you're not going anywhere, seeing anyone, etc and it just takes too much energy, don't worry about it.

I used to go days without showering. I just didn't have the energy. Now, the only reason I shower and bathe daily is boredom. I made it routine. They say bathing is less sanitary, but I bathe daily and deal with less infections now than I did when I didn't at all. Bathing helps me with the pains I deal with (chronic pain from depression and the eating disorder), and if you get pains, I recommend trying it. I found that simply making it a habit has made it go from a chore, to a way to relax. So, now I have the opposite problem. I bathe too darn much.

However, I don't think it's a bad thing not to. Everyone copes with depression differently, and I have been there. Not wanting to groom myself at all. Going days - in one case, weeks - without showering. I understand, and don't think anyone should beat themselves up over it.

As far as shaving goes, I don't do that, anyway. That is 100% a social cultural thing, and is optional. And if you don't have the energy to do that, it's perfectly okay. Just take care of yourself. Sometimes, we have to put our mental health and recovery first.
