My adult sister has spent her life being grieved , due to her belief I was our Dad’s favourite. She can’t forgive him or me for this. She is toxic towards me, e g. gives me the silent treatment in and can shout and belittle me. I no longer see her as it was affecting my physical and mental wellbeing. She claims to be a Christian, but I don’t think she is an ardent follower of Jesus. I want my sister to be right with God and for her to let go of her wounds, which are damaging. I believe she has narcissistic tendencies and will never be sorry abour her treatment of me, bar a miracle from God.
