When I have difficulty talking about something, I sometimes will bring up the topic, then tell t she needs to ask me about it, because it's hard to talk about.
Other times, I write it out then ask to talk about what's written. I start with a new t tomorrow, and have some stuff written out to tell her. Most of it is how I function, why, and what I'd like to get out of therapy this time around. I normal just get around to telling a t all this stuff, but my time with this one will be very limited, so I want to get right into things without that messy "getting to know you" phase...
