Some of those sound like they might be ADHD related, but could also just be a result of how you were raised. Were you like this at all or similar as a child? I dont know that the last two you listed are neccesarily ADHD related. They could be signs of social anxiety.

But I can relate to some of the items on your list. (I'm 25). It's probably worth being evaluated especially if its interfering with your school work and relationships with others.

Are you able to focus when someone is talking to you or do you sometimes space out and not listen, especially in lectures?
