It seems you spent your whole life caring for others - elderly relative, husband, sons including one with extra needs.
They all spent all that time with you firmly in the domestic appliance category in their minds.
I'm going to ask a provocative question - Did that care include teaching them all to fend for themselves? Or was that your role, your achievement, your status? Your equivalent of bringing home the money?
Then your husband retired. You didn't. You'll be keeping on working til you drop.
But unlike him, if you stop working, your own life gets grubby, messy, inconvenient, smelly, unfed, because what you do makes all the nice stuff happen 'magically.'
Your resentment will only build and build. Passive agressive quiet quitting will not work. They won't know what's happening because they haven't been re educated. They'll be mystified. Standards seem to be dropping. They'll think mum's getting a bit ... You know ...
Read up on assertiveness techniques.
Time for a family conference.
As I do often say, write it all out, refine and polish your statement til it's right.
Practice it.
Use authoritative language, tone, body language etc.
Tell them. What's happened, how you feel, how the changes in everyone's lives haven't been reflected in your own workload. What needs to change.
Set boundaries and expectations. What you will and will not accept.
Assertive, confident communication is what's needed right now. You've run a family = a business for several decades. You've got skills.
