Thanks everyone for your thoughts. I brought the subject up with DocJohn in the chatroom just now, and here's our brief conversation:

TheByzantine: I have started over many times .. .now I am told I have a personality that is not conducive to therapy
Medicated byzantine - I'm currently trying to decide if my issues with therapy can be helped by trying someone new, or if I'm just too "difficult" a personality
TheByzantine: therapy goes in a circle
TheByzantine: you make things too difficult .. .how do I make things too difficult .... you do not understand .... what don't I understand ... you make things too difficult .....
Medicated KDlady - I'm discovering that even if you want help, you may be unintentionally sabotaging your attempts. I know exactly what byz means
KDlady: oh that circle ... and that makes sense to medicated
Medicated what's the solution when you find yourself in that sort of therapy situation? (repeatedly?)
DocJohn: Finding the right therapist is just as important as finding the right medication. Especially if you're going to do one of these treatment options on its own. Not all therapists are equal.
DocJohn: You have to find one you can work with productively and that you feel comfortable with.
Medicated Doc - the last two are telling me it's my fault, which really hurts because I'm not meaning to be resistant.
Medicated so I worry that trying someone new would be useless
Medicated ... that I can't be helped.
DocJohn: Medicated... Yes, that's just wrong. And inappropriate.
DocJohn: Not sure what purpose "fault" has in psychotherapy... sorry to hear that.
Medicated they never used the term, but they ascribed the difficulties in the relationship to me.
Medicated "If you weren't so defensive..."
DocJohn: gotchya
Medicated thanks for your thoughts though.

I was a bit surprised at his reply, but I'm thinking more and more that you and he are right. I ought to find someone else who is more understanding of me and my needs.
