ADHD memes

I wonder what other mental issues/ deficit disorders have the "time blindness" as a symptom? I have that and it is a very specific thing to have, and I'm currently trying to figure out if I have ADHD or what I have because there are definitely things about my behavior my whole life that have kept me behind everyone else, noticeably to myself anyway. Stuff I've had to just cope with, but still puts me at a disadvantage. Mathematics for instance. I can barely do algebra and I'm talking high-school level, no matter how hard I try, and my memory is shit, and it takes effort to stay on topic, or to stick with the same thing I'm doing. I hate routine and crave novelty but lack of routine ushers the chaos back in.
