I was triggered this weekend. Thankfully, I didn't self harm or attack anyone else. My husband has been practicing some techniques to help with PTSD episodes. When I have them, I regress to a little girl, terrified and convinced I will be alone and abandoned. I don't know where it comes from in my past. I was neglected and abandoned by my parents, but I don't remember maliciousness. There was violence in punishment (whippings, belts, hands). I probably won't ever know where it comes from.
The good thing is I didn't harm myself or my spouse physically or verbally. I didn't run away either. Not a great weekend, but not as bad as it could have been. Progress.
