For me, it was finding a therapist that was big on "validation". Staying away from the key elements of victimization such as minimization, invalidation, degregation, gas-lighting, bullying, scape-goating, humiliation and I am sure there are many more triggers out there associated with keeping on in victim mode.
One thing to realize is that a victim can move into survivor mode and then hopefully into thriving. Thriving is where I want to be.
DBT has also helped me tremendously. Living in the present moment and radically accepting what happened to me in the past.
