For me, ADHD is all about overthinking and underdoing. A side of mild social anxiety, mixed with the bizarro state of the world, certainly doesn't help.
My lawn kind of needs mowing.
Today would be a great day, but I need gas.
And I can't stand the thought of someone seeing me filing up my gas can and thinking I'm one of those crazy people hoarding gas right now.
I'm 99.99% sure it would be fine. But that tiny voice worrying that someone would give me crap about it, or take my picture and post it with an insulting caption, is very loud.
I could just tell myself it's fine. The lawn could wait. There's a dozen other things I can do instead that have zero risk of public humiliation.
But will I do any of those other things? Doubtful. I expect I'll be spending the day trying to convince myself it's silly not to mow. Possibly a few days even.
The ADHD part of my brain has decided it's a great excuse to do nothing. I've decided to let it win today, and rest up for the next battle tomorrow.
