I have, but it wasn't a bad T I was processing, it was a good T (the best I have ever had, actually) who needed to terminate with me and did so properly (and ethically), but it was still a huge loss.
The T I processed the loss with was a referral given to me by the other T...they spoke on the phone in advance of my first appt., which was helpful, so the second T knew what was going on (and what he was in for, ha) before I arrived.

ETA: I have also gone back and seen my childhood T since seeing this T and she was a horrible ***** to me, so I processed that with this T as well (plus a few terrible pdoc experiences), so he has heard a lot about other Ts/pdocs, and has always been extremely supportive and helpful.
