This is a cycle I go through frequently. In my experience, there's sort of a relay race effect of rapid switching that's difficult to keep track of but it's like a number of us are racing to make sure this happens before I snap to and put a stop to it. It's difficult to even talk about in therapy but I make sure each T is aware of it. Getting to know the signs of what will cause it to happen has helped but like anything, there are a lot of triggers to recognize and keep track of. I agree with amandalouise. I don't want to tell you what to do because every situation is different and everyone's treatment plan should be carefully designed for them by someone who has the training and information to do so but I will say that finding constructive distractions that make me genuinely happy has made a big difference for me, not that it's easy to bring oneself back from those impulses. It's not easy. The fact that you recognize that it's happening and recognize that reenacting your trauma isn't the healthiest option for you is major and something to commend yourself for. I commend you for it. I hope you keep yourself as safe as possible and get to where you want to be.
