I am 13 and I think that I have ADHD, I have answerd yes to every symptom, and its not just the quiz thats made me think about it, for a while I have noticed that there are alot of things that I cant help doing, eg: cant stay in my seat in lesson and saying things quikley before thinking, resulting in detentions or no friends. I am scared to ask my parents/teachers, I know there is one teacher I can trust, because I tell him everything but Im scared he might think im being stupid about it and not take me seriously. What should I do?
