yeah, definitely bring it up. i totally understand your concern about not wanting to call 911 or go to an er when you're in crisis.

in the past, my therapist has been available through phone 24/7 (but i rarely called her unless i was really in a crisis)... sometimes it would take her an hour or two to get back to me and she'd talk me down. if i'm not really in a crisis but having a hard time, e-mailing her helps too... just writing it out and feeling like someone will actually read what i write helps me.
