One thing my therapist recommended was when I am in a flashback, or feel one coming on, to be honest with my children about it. If it is one I can work through to not hide it from them and to explain that even parents have difficulties dealing with their emotions. I'm not quite there yet, as I can not distinguish the past from the present when they are happening, but am hopeful I will get there soon. I felt so guilty when my son triggered a flashback from an abusive relationship. He is only ten years old and had no idea what was going on. Thankfully we are all working with the same therapist and he was able to explain it better to him. He told him it was like I was in a nightmare that I couldn't wake up from and that instead of seeing him (my son) I saw my abuser. We are working on boundaries to prevent this from happening again and so far that has helped a lot!
