I was finally diagnosed with adhd in college. Funny story actually.... I had gone to see my dr, and my 2 best friends (since oh, 6th grade) both worked in the office. I didn't see them until I was checking out, and they asked why I was there. I said, "oh I have ADHD." They look at me and say, "Yeah, we know. But why are you here?", like it was a totally unrelated point. So I told them, "Now it's official..and I have meds!" Their reaction? "Its about time!" Haha.
Anyway, the best decision I ever made was to talk to my doctor and finally get diagnosed. The meds, and initial therapy I went to, changed my life. I don't think I would be doing well in my career without the help. Too many distractions in the classroom! Plus keeping up with planning, correcting, meetings, etc.
