From the 1st post: “I think of myself as a tough cookie and life doesn’t feel as stressful as periods in the past”
That can be the first issue. That your engine runs at such a high level of ordinary/day to day stress that you don’t even realize how high, how constant, how it adds up, until something breaks. You’ve set a high bar for yourself. If most of us manage, say, ten things in a day, you’re at 30.
And even then, the tendency is to minimize. “Oh, but that wasn’t as bad as xxx,” or “I’ve held through worse.” That doesn’t acknowlege limits. Sometimes, the rationalization leads to forward stress: “If I don’t yyy, worse will come of it.”
This “always on top of everything” thing is exhausting.
Your husband seems to cope. You have that right, too. But I’d point out that getting “whole hog” into something isn’t balance, either.
In addition to great counseling (someone who supports parents of Aspies?,) and activities just for you, very “self” centered, you find some way to get help with the boys. A couple of hours, while you go to therapy or yoga, mindfulness, dance class, exercise, a museum, whatever just for the person you are. Something indulgent, not just another task, “regimen,” getting job homework done, etc. That’s ok.
Best wishes.
