Yes PLEASE talk to your guidance counselor or doctor. If you still don’t think they listened to you properly then keep trying until you get through to them or your parents. This is the only way you’ll know whether or not you have ADHD or some other condition. And it’s the only way you will get help if you do have a disorder. I’m 44 now and I wish to God someone had listened to me and gotten me into mental health treatment when I was a kid.
