I'm sorry you're hurting and feel unable to talk about it. The tone of the email seems quite emotionless and formal, although very proper. No one could fault you for not being polite. It's clear that you're cancelling your upcoming session, but not clear about any others. Do you have regularly scheduled appts? If I were T, I wouldn't know what your intentions were for any future sessions. Unless you have none scheduled, and in that case it sounds like you'll just call when you're ready for another session, and are not terminating completely.

Are you clear on what kind of response you expect? I don't know your email agreement with T, whether he would normally respond or not. But if you have some sort of expectation of a certain kind of response, maybe you should review the wording and see if you're likely to get it or not. (I have no idea about what this might be - just putting it out there because I've discovered I often have hidden expectations about responses that I don't realize, until I don't get the response that I want ...)

Also, I'm having a really rough time in T right now myself. So I truly do feel for you. It can be pretty hellish, actually .......

Since you're not asking for advice about whether to send it or not, I'll refrain from expressing my opinion.

<<go ... go ... go>> Oops! Slipped up there, sorry.
