If my W is bipolar, it is very mild. Your W sounds more severe. Paranoia and what the psych described as "suggestability" is symptom of bipolar. Somehow, I think the fact that she thinks you can put thoughts in her mind is a good thing. I think it shows that she thought a lot of your advice when she was well. Just let it go for a while.
What caused the therapist to say "you are not trying to get healthy"? What were the "philosophical differences". I often debate my counselor on things and he doesn't kick me out, doesn't seem right. In any case, best to get a new one anyway.
