This is something I struggle with a lot also; the anger issue but also what to share and what to not share. Something that struck me powerfully awhile ago is reading someone write something along the lines of ..... why are we in T if we aren't there to tell them everything? how can they help us unless we share? why are we paying them if we are keeping what we need help with to ourselves? (now remember i said I struggle with this also so no way am I saying any of it is easy).

It does sound like you need to share your anger with T ... see where it is coming from, how to process it, how much relates to what your T said and how much is other things also coming into the equation ... sharing this should be healing for you and part of the therapy; and shouldn't mean you are viewed as hostile although sharing that concern is probably something else that would help to address

(Just so you know, I'm in the same place with the meds / hard work issue as well)
