I am sure she will be appreciate that you tried.
Fear is what is behind alot of peoples problems, I know it is one of my problems.
As far as what to do with your feleings when you have finished your session, perhaps you can go home and journal...then bring in the journal the next time yous ee her so you can start where you left off and gives you something to look at and begin so maybe you will be more present and feel more productive.
Ilike the suggestion about wrapping up a bit earlier and recapping what was said and done, maybe you could ask for that?
it sounds like you are getting overwhelmed with the big picture and not focusing on the here and the now, remeber it really takes one day at a time.
