If you have changed your mind, and you don't want to do this, please tell your T.
You feel how you feel and that's okay. It's so understandable that we could agree to something, especially when wanting to please our therapist, then feel differently when we think about it more. You said yes, but have thought about it more and now you want to say, no-I've changed my mind. That's okay. Let her know and talk about it more.
