I can't control when they surface. My strategies when they arise, have been to try and push them away, avoid them, panic and react to them.

However, I am now starting to sit with them and observe them in a more rational way. Practice the grounding, relaxation stuff when they arise, tell myself I am ok right now, they are "just" thoughts, not happening to me right now.

However, with the images, I also have feelings towards the other people associated with them and feelings about myself. That has been harder to work through and I'm not there yet. But slowly (very), I have times when I can let go of the negative feelings. I think it just takes time and a slow chipping away of things.
