Chris'smom,
Welcome to the board! ADD is very often co-morbid with other things. They do all fit together sometimes. Its good that you found out about all of them and no one is trying to shove them all into just calling it ADD. Now you are in a position to get your child the help he really needs.
You are in the right place. We are all here trying to find answers and offer each other support. You now have a place to vent and ask questions, even offer help or advice! Take comfort in knowing you are not alone in this and you do have people to turn to when you need to! I really makes a difference!
