Yes Jen we have experienced the same with Evie as well. As Tammy says, not necessarily anger but definitely a mood change. I don't believe it's easy for anyone to go to a doctor or therapist, and in someone with PTSD it can be most difficult. I know Evie has anxiety and gets triggered. Not to mention if the psych is doing therapy with your husband, he may well feel out of sorts afterwards, though that is a good thing. That may sound odd to say, but it indicates he is working on his issues.
