My T literally said to me once "You can talk about anything you like in here. You could talk about jelly sandwiches if you wanted to" haha. I do know what you mean though, I feel as though I can't ask T questions about herself. The sort of things I want to ask are if she sees her own therapist, why did she choose to become a therapist and what made her choose her particular modality (psychodynamic self-psychology). T may not answer the questions but I should be allowed to ask them.
