I have done this many times, leave important topics to be discussed at the last minute. Usually they would get a little annoyed just because there wasn't enough time to process it before session was over. They didn't know that inside I was having a running debate whether or not to share, would i end up humiliated or would the t try to shame me, this is embarrassing do I really want to talk about it etc. Maybe when you start trusting more you will share at the beginning although for me it took forever to share a lot of things because of the dialogue running through my brain.

It happens to the best of us.
