I have it pretty bad. I did damn well in school, but had a lot of social tics and issues remaining still and waiting my turn for things. My coping strategy was literally to bite the inside of my cheek. It actually makes me social anxious that I'll spew some retarded nonsense or simply walk off, while someone else is speaking.
I also am very slow on doing assignments and labs, which I have to put very concerted effort into, and have to be meticulous about scheduling, or else I simply don't do it. I am very absent minded about quite a lot else.
I'd like to describe ADHD is like having white noise in your mind always. The amphetamines clears that noise and allows you to do things and actually schedule ahead ect....
I hate the quirky turkey random fucks that think they have ADHD because they want to look special in front of their friends.
It fucking sucks. I hate it. I'd do quite a bit to get rid of it.
