I'm so sorry Nightsky. You sound so overwhelmed, and it can't help to have what used to be a major support -- T -- be on such shaky ground.
Make sure to make time for yourself during the day. Don't let yourself drown in everything that is going on for you.
As for the phone, I had an unexpected broken phone a few years ago (got hit by someone on a bicycle, while I was in a crosswalk, jacka ss -- anyway the phone was in my back pocket and I was thrown backwards), and almost instantly, as soon as I told my girlfriends about it, I got offers of old phones from them. I actually got my pick of phone models! I didn't (and don't) have a smartphone, so that made it easier since there was no data plan to worry about. But you'll find a way through it... just don't forget to let your friends help you.
