Does anyone else have flash backs from an abusive relationships?

Before someone advices therapy know that I have looked into it and the cost of it is insane even with health insurance.

I will randomly have really really bad flash backs of my ex hurting me and I just go into this trance with this heavy feeling because I can’t believe that happened to me, that I let it happen, and I feel so shit about myself. I really struggled with this a lot.

Being in a domestic violence relationship just rots your brain and I’m in a major major part of my healing almost 2 years after healing and I can’t stop these flash backs.
