Yes, he is in therapy for a mood disorder already. I worry that he doesn't utilize therapy to the fullest extent. Also, he only goes every other week. He did make mention of my daughter's behavior triggering him.
I also have PTSD, and really feel scared inside of his anger. It's hard enough to deal with problematic behaviors of a 12 year old, without these other dynamics. I feel that I have been doing quite well with my daughter, and I feel very protective of her, even while she frustrates me to no end. I need support, not another person behaving like a child...bigger and stronger, and more intimidating though.
