At the moment, daily, usually when I'm back at home after a work-day that has driven me apeshit crazy due to the people I've had to deal with, and even some of my recreational time being constantly ruined now by intrusive people.
I too am needing much, much more alone-time just to recover from or prevent future ones. I always did need it but it's worse lately.
If someone in your life with an autism spectrum disorder seems to drop out of contact for a while, it's likely just them needing time away from everything and everyone just to keep functioning.
Back during a time when I had more areas of my life under my own control and a lot more was "on my terms" rather than on everyone else's, I was much better, with meltdowns and shutdowns much more rare. I still experienced agitated after-effects of too much socializing, but I seemed much better able to cope, manage, handle, recharge my batteries faster, etc. than I can now.
Getting older and having some life crises that caused me catastrophic stress has made my adverse effects worse than they used to be. That was partly what began to cause me to face up to what I'm dealing with at the root cause.
