I've gone longer than that without a shower...depression can kill motivation for anything really. Though in general if you aren't going anywhere/have no one to see I do not think it matters so much unless it gets to the point you feel dirty and want one...sometimes a bath is easier than a shower since you can lay there instead of standing if you have a bathtub anyways.

I also don't shave everywhere...but that's not just due to it taking too much effort even if I have the energy I don't...so its mostly by choice. Some people think even a showered/clean female with body hair is gross...don't really get that its not like women with hair avoid applying soap to said hair.

As a teen I gave in and shaved legs/arm-pits whenever I could muster the effort(had depression since i was a kid so still had it then) or would wear clothes to not show if I hadn't to avoid getting made fun of for hair being female, but not anymore except arm-pits in the summer when its hot since I sweat quite a bit and then they itch and that's it...But really its not necessary for hygiene, a simple shower is enough so times when you're really having difficulties maybe just sticking to basic showering nessesities like hair washing, scrub up with soap rinse and then its over with. I guess for me with a lot of things sometimes I might end up not doing something I should because I can not do it as completely as normal...so sometimes just worrying about the basic necessity's of the chore helps make it a little less overwhelming.
