I think you should take some deep breaths and don't let the "cart get ahead of the horse". As you said - your therapist is a human being and made mistakes too. It's not fair to read more into this - like she could be a ***** too.

You should be honest - maybe she doesn't realize this info can be obtained on Google. Let her know what you found and see what she says. She can still be a good therapist and she shouldn't be judged on this info IMO.
