Whenever I have something I want to talk about but know it's going to be hard for me to start, I email t and just tell her in the email that I'm afraid I will chicken out so here it is and please remind me to talk about it. She won't bring up the actual thing, but when it becomes obvious at the next session that I'm not going to bring it up, she will say something like "so you sent that email..." or something similiar. So I know she already knows the topic and I can talk about it.
