you probably know this already, but spacing out like that = dissociation.

Just a thought--I know that you like your T and all---if you see T 2x a week, instead can they help you NOW to transition to a T who will be around longer? So see regular T once a week and see a new t once a week?

You probably know by my posts that I purposely see two t's---sometimes one can be great while the other one is having an "off" week. Having two perspectives is interesting too.
Don't know if you'd be interested in asking your t about that sceario, with the goal of eventually seeing 1 t twice a week.

Just seems that you are justified in your worry about your upcoming loss of t. Seems it would help to get attached to someone else now not later??
