Since about the age of 7 yrs. 6 months, my previously happy 8yrs. 4 months son has been anxious and angry. He's afraid of elevators, theme park rides, the dark, etc. He has also been angrier than before - is easily angered, even over little things like being asked to turn off the TV or come to dinner. He has been diagnosed with ADD and is on stimulant medication, which does help him focus. I don't know if the anger is all related to the ADD, or if there is more going on. He does have friends at school, but I worry that he will lose them if he can't learn to manage his feelings.
