Sorry I wish I had something new to tell you. I write it all down if I feel like that, but directly. A real example...last week you asked a question and I didn't answer it fully because I didnt think about it properly at the time. So I wanted to clarify and fill in the blanks.
(I write in bullet points to get each point across and to break it up so it isn't a solid 4 page letter.)
Then I go over everything I have written, just so I know they get what I'm on about. And ask for their input. If I don't understand something I immeadiately say, can you repeat that in English for me please? (I hate psychobabble)
Most t's I've had have been pretty good with me about it.

I hope you manage to find a way to deal with this.

Ps you don't suck at therapy. It's a difficult thing to do and you are sticking with it which is good, although it sounds rather frustrating, but I had a really good t and I found I got rather frustrated with myself and with her at times.

Hang in there....
