And did you explain all this to the therapists? I mean as people said, they can't solve non-mental health issues. If they tell you to set boundaries I presume your response would either be "I've tried and it doesn't work" or "I don't want to try because the risk is too great". At which point I'm not sure what they can tell you besides "Get out of the situation", if it's the situation that is causing the mental health problems to begin with.
