your not dumb, I was diagnosed with adhd as a kid, which is unsual for them to diagnose girls, I did have the hyperactive along with add, and from what I read in some articles latly, that is not common, I was called a tomboy too as if that was a bad thing.

I thought I was just lazy or something, I did not know that going from one project to another without finishing them is ADD related or daydreaming even when I am involved with something I find interesting, maybe mental fatigue? how about forgetting to do something or turn something off when you are intent on doing it only to refocus almost without realizing it until you realize later did I turn off the water? did i put this or that away I knew i was walking right over to it in a second or two and yet I drifted off that fast.

and I have done that look over something several times to find mistakes etc, and missed them so you are not alone, and no one is dumb just because they don't measure up to what society says you should.
