I wanted to introduce myself and say hello. I have a daughter (14) who has ODD, ADD, Impulse control problems and some substance abuse problems. My husband and I have no other children, and our hearts are breaking. She is in a dual-diagnosis treatment center, and not doing well there either. She was always a good student and never gave us problems until 2 years ago. At the same time, she suffered a concussion and severe thyroid problems. I am glad I found this forum, and look forward to giving and receiving support. I belong to another social on-line forum, but we use different acronyms. Can you tell me what you use for daughter ect? Thanks so much.
