My view is that you have to take responsibility for your childhood, because even though you were a child those patterns are still in you today and realizing that they are internal is key to fixing/healing them.

When we shift to gratitude for our particular story, our "weaknesses" become our best gifts. I was a victim for a long time. Now I feel like my story is the best one because it makes me, me. My favorite person. I take care of me first. That makes it easier to help others.
Blaming yourself for a tough childhood and taking responsibility for a touch childhood are not the same. The former is punishment, the latter is empowerment. The former is, "I deserved it," the latter is, "I didn't deserve it, but I'm also responsible to find my healing." The former is about accepting lies, the latter is about accepting the truth, and allowing God into those spaces to show you the truth about yourself, and Him. Because the truth about you and God will heal you.
