There seem to be a lot of different issues going on between the two of you - almost too many to cover in one session - I definitely think there would be value in discussing them.

I personally feel that things are better saved and bought up in person, there is something very different (and more assertive) about saying things in person rather than writing them in an email, however hard it is, and it seems more real in the relationship to say them in person rather than write them - you get both of yours emotional involvement and reaction if you say them in person.

Your T says she feels you in some way control or want to control what she says or doesn't say. I think this may be a really common thing, I would like to control what my T says to me, she has reflected this back to me in a different way to your T, but I recognise it as the same thing.
