When my H was having lots of complications from Stage 4 gastric cancer (at 46, he only lived 4 months after diagnosis), I spoke often to my T via phone, especially when I had to miss appointments for emergencies. I felt like I was in crisis after crisis, and it was good to have the ability to talk-- rarely for more than 10 or 15 minutes-- to just say this is what has happened and boy this is hard to cope with. Being able to reach him, including after hours and over the winter holidays, was really helpful to me. Outside of that time I have rarely contacted him after hours.
