Hi shunshine88, I was diagnosed with ADD actually after I got out of High School. Looking back, I could totally see it, but since I got good grades and stayed out of trouble, nobody ever thought about it. I started college and had a hard time with concentrating and studying for tests (not to mention I was going through a manic phase) but when I started taking adderall it changed everything. I was also diagnosed with bipolar disorder at the same time. I did very impulsive things before I got started on the medication, but I'm not sure which disorder caused it. You might want to get them to check for anything else if you go to your doc for ADD. Just a thought.
