I really disagree with ts promoting forgiveness. Who the he’ll does your t think she is that she can spout that kinda crap at you.
I am sorry I get so annoyed but nobody can say whether your grandma needs to be forgiven only you and it seems like you are only beginning to process the horrors of what she has actually done to you.
Your t is completely invalidating and dictating your sessions. She wants you to talk about the sexual abuse next week, I want to win the lotto but that doesn’t mean it will happen.
Do you feel your t is in charge because this is your therapy and you can talk about what you need to and when you need to.
Your feelings matter too. I am very angry at your t. How do you feel about your relationship with her?
