I'm so sorry you are going through this phase of CPTSD. It's awful.
Putting them out of mind probably isn't the best long term because the content is coming up to be processed. If they are so bad you can't speak about then you can also try to get them out here in writing.
I understand, not being able to speak of them. Some of my nightmares have been so horrific that the only way I could speak of them with T was doing flash EMDR first before even trying to share. There's no way I could even say anything about them to anyone else.
