An interminable torture (dysfunctional family troubles) help?

Your letter could have been written by my grandson. Son, this man is mentally and physically abusing you to the point that you don't even like yourself or feel worthy. Before you let him destroy you, go to a teacher, counselor, clergy, anyone that can act on this for you. You need to be separated from your Father. Child Protective Services are the people who can get this straighten out for you. You are too vital a person to let this keep going on. We out here the readers are pulling for you and want to see you relaxed and happy.God Bless You! A caring Grandmother.
