I haven't had an emergency/crisis session, but I recently had a midnight phone call with my T. I thought of that as a crisis situation because of how badly I was feeling. With it being midnight, we just talked on the phone for 15-20 minutes. I'd had a sort of crisis thing a month or two before that, also around midnight, and had been unsure whether it would have been OK to reach out to her or marriage counselor, like what exactly constituted a crisis where they wouldn't be mad that I'd called. They confirmed that in that situation or a similar one, it would have been fine to call. (Reasons in this case are under trigger warning below.)
