Do you have an idea about what is making you most uncomfortable? I struggle a fair amount with anxiety in sessions and my T works to try to keep me within what she calls the "window of tolerance," where I'm not over-activated, but also not under-activated. It tends to slow the process WAY down, but it's helpful in terms of helping me to get stuff out.

I think that asking for a picture is a great idea. I've asked my T for one, and she was perfectly fine with it.
