In my own opinion for myself, I would consider a crisis if I felt extremely emotionally overwhelmed and didn't know what to do and had no one else to turn to, I'd call my T. I did ask for a session on a different day once because I had such a terrible week, and she had cancelled our session because of a holiday, but I don't necessarily consider that an emergency session.

That being said, I called my T tonight and left her a message just because of how cr@ppy I feel about something, and she is always reassuring me that it is ok to call and e-mail her, even though I hate it/hate feeling needy.
