I echo Can'tExplain's post. My therapist (I've known 5 years) has made mistakes and apologised in a similar fashion.

Could it have been that she wanted this person for you as she felt they would help, but hadn't consciously taken in the specifics before telling you?

You've spent a lot of years with this counsellor and you've obviously been through a difficult time.I really think you should question your counsellor and speak about this more before throwing everything away
