totally possible
OCD is complicated. It's not like a binary diagnosis where you either have it or you don't. I exhibit a whole lot of symptoms of it, but it's not severe enough that it really makes my life worse off. So if you're not sure, but you think you might, you might have a mild case of it.
ADD (in my opinion) is just a made up word for someone who's brain works different than sitting quietly in school for 7 hours a day. Fake fake fake. Just an excuse to sell more drugs. Didn't Thomas Edison do badly in school or whatever? I don't remember, but they totally would just diagnose him with ADD and stick him on the drugs these days. I think I might have it. I don't want to get a diagnosis (cause I don't want drugs, I don't want the label, I don't think it's actually a deficiency or whatever it's just different brain function). The education system just does a bad job and blames it on ADD/ADHD when kids struggle in that environment.
