I'm sorry she read your diaries and you are stuck there. I would send a really short email explaining that and asking for an earlier appointment. My T also has boundaries about email and contact outside a session, I have only contacted twice. I think this is one of those times when contact is ok. Also I think there's a difference in an email that is an attempt to do therapy outside a session for instance expressing anger (I'm afraid both times I contacted My T it was basically for this) and am email or contact with your T which is reaching out in a pain and crisis and communicating a crisis.
