...with different Ts?

I don't want to keep reliving the experience. I saw a therapist while I was going through my breakdown and talked quite in depth about what was going on for me emotionally. I didn't feel I gained anything positive from it other than having the support of the T while I was going through it. However years later I'm still not well. My current t wants to talk about how I felt during my breakdown but I am struggling to see what more is to be gained from doing so. Surely I'm just re-traumatizing myself by talking the worst time of my life?

Can anyone explain how it's supposed to work? Has anyone had any positive experiences of keep going over old ground with t after t?
