Fellow man pushing 50 here. I'm caring for my mom who has COPD and is starting to show signs of dementia. She lives a couple hours away and I just started a job that's 3-4 hours in the opposite direction, so I'm balancing a long-distance weekly commute along with weekly trips to cook, clean, do shopping, etc. Due to how this eats up most of my free time, it's actually made me better at squeezing "self care" into my schedule since it's become clear that it's not something I can defer to later, since "later" may not come for several years.
It's not at the same level as your dealing with, so I'm writing this mostly to offer support and to be glad that you've found some activities to help center you. I do encourage you to try to find some help, even if it's just for some small part of the care, like cleaning, shopping, bathing, whatever.
