yeah I do have tips. For me it was key to start fairly slow and have some kind of way out once the conversation got too intense for me. That way, I didn't just build and build on the anxiety.
Also, I think T may be trying to get an idea of where your expectations are regarding this. If you're feeling pressured by the WHY part of this, when you get to the WHAT, your tension might rise like mine did and in that case, it's imperative (I think, just IMO) that you should feel safe, and feel that there is a way to slow down the process if need be.

And of course, hats off to you for having the gumption to take this on!

Go at your own pace!!! take care of yourself. You can do this!
