I’m the same.
I have a late diagnosis if ASD which hasn’t really changed anything per se, but it does allow me to be more gentle with myself in terms of how often/how much socialising I can cope with. A day with friends sees me utterly exhausted because I have to work so hard to be “normal”.
I’m 59 now and frankly, I do less because I think “I just don’t want to do this/that”. I can and do make the effort but I’d far rather be at home with a good book and a cuppa. Even the kids/grandchildren are hard work at times. It’s definitely not just getting older and more tired. I still work hard; am very busy but I find myself needing to switch off from the noise/life/engagement more and more.
