I was diagnosed in 2019, at the age of 39. So I have a lot of work to do to unravel all the 'coping' mechanisms I've taught myself over the years. But what's been most eye-opening is my shift in perception of what ADHD is from something that naughty boys at school are told they have, to this thing that afflicts my brain which causes me to forget everything all the damn time.
And the best part is when I complain about this, and some well-meaning person will say "Have you tried using X.app?" and I'll go to download X.app ONLY TO FIND I ALREADY FUCKING HAVE IT, THAT I USED IT THREE TIMES THEN FORGOT IT EXISTED.
And it's all just so fucking exhausting.
