Sounds like you were giving your therapist positive feedback about how you were doing so she was as surprised as you about the downward spiral. Yes, she may have known it was possible but was buoyed with hope by you that you were on an upward path. Would you have preferred, instead of echoing how great you were doing, that she questioned whether this was really true, like she wasn't believing you?

I wouldn't blame it on her--but let her help you pick up the pieces and get back to where you were....
