I'm glad your OT backed you up. That says a lot about your OT, a keeper I'd say. Finding the right counselor, therapist, etc. is about finding the person who can guide you to help yourself. Having people out there who shouldn't be practicing only makes finding the right caregiver for you a little harder. You have the right to reuse treatment from anyone who you feel is a threat to your receiving good care. A professional who's tarts out blaming and judging you, when they first meet you does not deserve to treat you and you don't need to feel ashamed or fearful about that, ever.
