Oh, hon, I know that heartbreak! Please have him diagnosed by a competent professional. Look in your phone book for a clinic, ask your pediatrition, look on the web at some of the ADHC sites for recommendations. There is help & support out there. Meds won't fix it all, but they may help. And DON"T blame yourself! It's not your fault he has this condition, and you've been doing what you thought best. It's not working, so it's time to do something else, that's all. (((hugs)))
