Just more support here. I was having similar issues with overstimulation and being near a breaking point recently. I took two weeks off from almost everything. It has been so nice, I've left the house I think three times in the last two weeks. I am now feeling much better and ready to re-engage. So I also support cancelling everything for a while.

Also, to maintain health, I recommend scheduling regular rest days into your schedule. These are days where you don't leave the house and don't do any real work either. I need 2-3 of these a week to stay functional.
