I am 17 years old female. The past two years I have been finding it really hard to concentrate on school work especially if it is a subject I dislike. I often find myself day dreaming and once the class is over I realize that I did not learn anything. When I try harder to concentrate I get a headache. I get worried a lot, get distracted easily and I have a very low self-esteem. I have many friends but I sometimes piss them off by saying rude comments without thinking first. My close friend told me to go have a check-up with a doctor but I do not want to confront my parents incase im wrong. Are these any symptoms of ADD or could it just be something psychological?
