I've also done it where I said "Someone important in my life hurt my feelings...", referring to the T. It's a method for opening the door on the topic, then you can walk in. You can make it easier on yourself for the getting started.
Another method: email ahead of time that you want to talk about a situation but you are not sure how to start, since it involves you and T. What does T suggest? In this way, the door has been opened a crack before you arrive and you may be able to move into the topic more directly.
Good LUck
