I'm still in the process of getting diagnosed as an adult, but I generally say that I have a bunch of anxiety keeping the ADHD in check.
Like, I'm not late for appointments... But only because I have 12 alarms and didn't sleep the night before and any sleep I did get was populated by a fear that I was going to oversleep through my appointment and then I still left too late to make it on time so I ran.
My assignments aren't late... Because when I realized I put it off too long, I stayed awake all night writing in a panic, and I only reread it 8 times instead of the 12 times I wanted to.
I don't lose things... Because I put them in the same place, every day and if they aren't there I get a little panicked and can't find it, even if I walked by it multiple times.
Speaking of walking by, I need to try and do things the first time I see them, because if I let myself sit down, that chore vanishes.
The last chapter is less angering. I had to skip to it, I couldn't finish either
