skysblue, it's nice to "see" you again here though I'm sorry you're feeling "dumb". My feeling is that if you thought you needed an extra session, then don't second guess yourself. For whatever reason, you wanted it, so just do it and see what happens. Maybe you need this time to process and prepare for the upcoming event. Your T won't look down on you for scheduling the session. She'll just see at as something you needed to do for yourself, and won't analyze how much you needed to do it, or if you changed your mind, or what.

On the other hand, Ts don't care if we are "wishy/washy". Plus, you shouldn't be concerned as to "how you look" to your T. So if you really want to cancel, then do it. My gut feeling is that you should keep the appointment, but I'm not you and can't make that decision for you. Good luck whatever you decide.
