You don't have to stick to the "plan" for what you were going to cover in therapy tomorrow. Things come up and you need to work on what is most important for you now. It sounds like tomorrow is not right for disclosing your memories of past SA. That's OK. There will be another time. Tomorrow, maybe you need to talk to T about his actions so that you can start to repair the trust. It doesn't matter if you had planned this session specifically for dealing with SA. Plans go astray. Stuff happens. Go to session and don't feel forced to stick to a plan that is no longer appropriate.

That's a good email you sent. I think this is such an important topic that it is best to do it in person and not over the phone.
