Getting out of victimhood

I choose victims thoughts the majority of the time, which generate anger, resentment and unhappiness. Intellectually I know I am choosing these thoughts. I know there are other options but my brain rejects them. It wants to stay in victimhood, I guess because it is easier. How do I start to climb out of this? I’d it thought downloads and models everyday? I’m afraid if I stay in my current thoughts and feelings I will create the same horrible results in my life I’ve been creating for the last 5 years.
