My son started having issues at about that same age and really, he was a bright, energetic boy all his life, its his personality. The school started having issues prior to my noticing it was a real problem. He didnt pay attention or stay on task. I remember one time at home I had instructed him that he needed to clean his room and he had this huge fit, to the point of me yelling and locking myself in a room because I was so frustrated. We had a lot of situations like this. Once he was diagnosed we put him on Concerta. Fortunately we found the right meds and dosage right away. Instantly we seen a difference. It was night and day. It was scary at first to put my small boy on a drug that potentially had negative side affects but after seeing how well he did while on the meds I felt so terrible for not doing it sooner. We yelled at our son for years for things and behaviors that were simply out of his control. His quality of life, of having fun and being a kid were definetely impacted by it, now that he is on a medicine that helps balance out those chemicals in the brain, he functions much better and can be himself. Another parent with ADD once explained to me that to a child with ADD (ADHD) cleaning a room is a huge task, one that seems absolutely impossible, too huge to actually complete. For a child with ADD it needs to be broken down into smaller, comprehendable pieces: take out the trash, put your clothes away, make your bed, etc. Once I got a handle of that it made life much easier. My son is almost 15 now, good luck with your diagnosis, you are not alone!
