I am not diagnosed yet (but I am with a ton of other things lol) but I think I have obsessive compulsive personality disorder. Most of the problems I have while on stimulants aren't ADHD related, I'm on a good dose/concerta is amazing.
So I'm very organized, hyper sometimes but I do not push my limits because I have every type of anxiety holding me back from blurting things out, etc, unless I'm super comfortable.
I can make decent grades on/off meds. A couple weeks ago I couldn't get myself to do any homework, especially readings for class, and I had a major essay due in two hours. I'd read one of the works the night before, we were supposed to use two or risk failing because it'd be too hard to make a cohesive argument without using at least 2 authors and a minimum of 1000 words. I was at 1,200 ish words and only used one author and got an 85. Considering how bad I thought the essay was, I am happy. No time to edit/revise. Just spewing things out and hoping they make sense.
The stereotype I did fit came later- she noted how my thesis was extremely strong, but the rest of my paper was kind of all over the place, even though some of the arguments eventually came together. Sad face.
Even when I'm distracted, I'm not off in lala land. I'm very curious/inquisitive and like to know how everything works and why. Except I'm obsessive so I won't stop until I feel like I fully understand. Ask me anything on betta fish/skincare basics and I could go on all day. I'm thinking about what I'm going to Google/research whenever I'm out of class/meeting/etc.
Not failing at life/not having any motivation at all. I do have minimal motivation off meds, but I know what I need to do to ensure I have a good future. I didn't know I had ADHD until my junior year of high school, and wasn't on a high enough dose until a month into my freshman year of college. I managed to pass 5/8 of the AP tests I took, one of those before I'd ever taken stimulants. Before stims, I was making straight B/C's most of the time (preap classes), minus electives. Started stims junior year, had straight As in all AP classes.
I may not have worded this well/in a way that makes sense because I fit the stereotype of not being cohesive 70% of the time. I swear, it makes sense in my head.
