I simply don’t finish work if I am spent. If I do, then I am worse the next week. I have the luxury of only needing to take care of myself.

Ask to hire for help. The business case is: either you break down, and the company loses a valuable person, or they get extra hands and can resume business operations. And while you’re at it ask for a pay raise because you were likely underpaid.

Ageism sucks. See if you can look younger or see if you can work at a company of a linkedin connection.

I am just brainstorming, you know what might apply to you.
