How do you cope with feeling helpless/weak?

Sometimes endo makes me feel like I’m barely a human being. Being so reliant on my family for support and having people just assume that I’m lazy. Even small things like going to the bathroom can be so so hard and painful. I consider myself to be a pretty strong person usually, but this condition has me feeling so weak and helpless sometimes. Does anyone have any coping strategies for days like this? It’s hard to be lenient like “well I just need to rest” because I always need to rest and I don’t want to just rot in bed. How can I be okay with not being okay for the foreseeable future?
