Reframing.
The past is not now, not the future. Yes, what you went through was traumatic, but it is in the past and you did go
through it not die from it.
By reframing the thinking, the thoughts, you reteach your brain how to file those memories. Once they are "filed" they won't always be forefront in your mind, triggering etc. They won't be gone, but will be there for when you want or need to take them out, review them (maybe adjust them some more) and put them away again.
You might continue to work on them right now by telling yourself, "One day you won't bother me." (To your bad memories.) That begins a reframe for yourself, your brain to create a file folder... where you can begin putting those memories.
It's tough to have needed to be rescued and not be. It's not easy to think you have to rescue yourself now.
