I find that I have lost some trust in my psychologist because she didn't help me to catch this latest spiral down into severe depression and anxiety again. Is it fair to hold your therapist responsible in this way?

Truthfully, before this hit this time I thought I was doing great, so that's what I said in therapy sessions. I was working almost non-stop, disconnecting from myself and my family. And she was just reflecting back what I was telling her. I guess I looked pretty good at the time. Then it hit, all of the sudden, hard and fast. I always spiral down super fast, within a day or two. And that's what happened.

Does anyone have any thoughts or experiences on what happened to me or on what is fair to ask of a therapist as far as your depression goes? Are my expectations unrealistic? (That's an issue I have so they may be.)
