(((((Squiggle))))) Don't appologize for feeling angry! This is the RIGHT place to feel that. It is OK to be totally ticked off right now! And PG is right, we are on YOUR side :-) So is your T ((I thought you may like that))

You are working very hard on feeling this anger - and that is a big part of therapy.
There is a reason you are having this response to your T not doing therapy the way you want her to do therapy. There is a core issue this is touching. It is also hard work you are doing by posting here and being so honest. ((( That is a GREAT job!)))
And that is touching a nerve too.

You are on the verge of a very big breakthrough - that is my sense of what you may be experiencing. Allow this RAGE to be what it is. Don't hide it. Don't deny it. Go fully into it and watch it. See where it takes you. We are there with you on this path.
