Ptsd and trauma

I have been using the model and thought work for over a year and it has completely changed my life. I have one remaining “old life” issue that I’m having a hard time processing through the model, and it’s holding me back from growth I’d like to see.

I have old trauma and resulting ptsd. I deal with my issues ok some times, but in others, I am unexpectedly triggered and find it extremely hard to recover. It’s very hard for me to “do life” when I experience this, and it often takes me days to recover. I’m learning not to judge these times, but they are still really disruptive to my life. How can I process quicker and stop feeling so bad when this happens?
