It sounds to me like she is following the rule of being positive yet neutral in email. She has a point. She has to be carefuly what she says in email because it can so easily be misinterpreted. It's also not private, FYI. Just wait for session and bring it up then. Try not to read anything into it at this point. My T, when I call him in crisis, always makes an appointment. He won't talk to me much at all on the phone or do any therapy either. It's just not a safe way to do it for either of us.
