Diagnosis is very tricky at such a young age. Talk to your son's psychiatrist and counselor about getting a formal assessment by a psychologist. The psychologist can rule out developmental delays, autistic spectrum disorders, etc. The findings of the psychologist can then be used to guide treatment with the counselor and psychiatrist. In addition, if a specific problem is identified (e.g., developmental delay) he may qualify for special services through the school system.

I know you are struggling, but I see it as very positive that you are seeking treatment while he is still young. Imagine how much harder it is for families who don't seek help until much later.

Consider seeking some individual counseling for yourself, as well. This is a hard situation to cope with and you are no use to your child if you are completely burned out.

Best,
