One thing that helped me was in knowing that God already knows everything. Since he has forgiven me I can forgive myself and my abusers too. I am no longer held by the chains of guilt, shame and fear put on me by the evil one, and am now learning to see myself as God sees me. He defines me, always has, and I no longer believe the lies that "they" defined me.
“We can easily forgive a child who is afraid of the dark. The real tragedy of life is when men are afraid of the light.” - Plato
