Peaches,
I think that's a big part of why I don't email T.
I know that I'd have such anxiety waiting for the reply and then the possiblity of not understanding the reply or even worse-- feeling hurt by it -- would be just too much.
I think it would hurt the paper thin connection that we have worked so hard to build.
I have a history of much trauma and relation problems - trust is not anywhere near strong enough to allow such a fickle communication process.
I think seeing and hearing what a T. is expressing is so important for some, and anything other than that can damage progress and/or the relationship with T.
I saw a psychologist in which I was able to email and he thought it would help me as I tend to not be able to express myself as well in person as with email..... but in the end, I believe, that is partly what brought the work to an end.

I could never build up the trust I so needed, as I had too many questions/frustrations every time about some email expression.

I left one day and never went back--no goodbyes- no anything-- after meeting with him for almost 3 years. I know the T. meant well-- but it was NOT what was best for me..... I see that now.

whatever you decide I hope it's what works best for your healing and inner-peace.
