Well, you do have a specific problem--your therapist! I imagine it's not all that unusual for someone to see one T to deal with stuff from another T (it's been mentioned numerous times on the boards). I would just mention that early on in the session and ask if she feels comfortable discussing another T. If she's a good T, she won't take what you're saying about another T personally. And she should be able to handle whatever emotions you bring into the room--even if directed at her--without getting defensive. She certainly shouldn't expect you to be nice all the time... But I'd be up front with your concerns. Good luck!
