I think it would be a very good thing for you to change Ts. Both as a client and as a practitioner. Your cognitive dissonance about starting a thread shows you need a safe space to process what is happening here. Being a T doesn't mean you are capable of dealing with her stuff. I am trainee and I know my T would never, ever burden me with his stuff, now or in the future.
I can't tell you what a difference finding T2 made to my wellbeing, Mona. If I had stayed with T1 I am sure I would be a poorer therapist for it. (I don't mean to say I think you are anything less than a wonderful therapist, only that having a healthy therapeutic alliance as a client can only improve your own emotional wellbeing, and inevitably your practice too).
