I've found it best to make my reactions verbal during therapy. So that if you're wondering in the moment what she means by it, ask. You don't need to do it in a hostile way. But the formula "When you [ask if I'm ok at these times], I feel [curious as to whether....]"

My therapist is very open to answering these in session type of questions, because it keeps me from forming wrong conclusions without verifying them. Which is part of therapy when you think about it. Learning to be open in communication.

Mind you, I'm not always pleased with his answer. A lot of times I'd rather think he was being artful and probing, and discover that he wasn't thinking at all.
