I believe you.
I’m 50, got diagnosed ADHD a month after I turned 50 in October. Yep, do I ever identify with your list. I’m no doc, but I think your instinct is right.Find a doc that specializes in ADHD, IMO, and attack this…and set yourself up for an improved second half of life. Because knowing is a good portion of the battle..once diagnosed properly, you will be in a better position to adapt. And maybe most important, cut back on the critiquing of self. Because guess what? You have been doing the best you could, all this time. And that is all we can ask of ourselves!
