One thing to consider is having a reason to live. Find something you care about or are interested in an leverage that interest.

Think of it like a car. Making explosions doesn't actually do anything for us in terms of getting somewhere, so we have to make a complex machine to turn that force into motion. I have an interest in electronics, so making electronic things to, for example, weigh my washing basket to tell me when to put on a load will turn some of that interest into activity.

As for nobody getting it, my partner does. They are my rock and they need me, so double win there. When I am having overwhelm they don't judge or condemn, they actually understand and help me find my calm and get things sorted. It took a lot of luck to find my partner and years of working together to be functional but now we are like an engine and a gearbox. They help me convert my efforts into useful stuff. They also help me know when to take a break and rest. Maybe something similar can exist for you?
