My T and I don't use e-mail, so calling him is my only option (which is perfectly fine with me). I don't have a problem calling pretty freely during his work hours, but in the evenings and on weekends I really take some time to decide if this is something I can work through on my own, even if it is uncomfortable; or if I am in true distress that I can't cope my way through, particularly if I am suicidal. It isn't a terribly difficult decision from there.
