I'm sorry you and your family don't get along. I couldn't imagine.

Not even a cousin or anything that you could talk to?? If not, maybe you should go to their place. If you guys have been exchanging cards and all, there still must be love there, and if they are around I'm sure they would be delighted to see you. If something awful happened, which I'm sure you could find out from a neighbor, you will at least know and know that you tried to contact them, and they will know that as well. Best of luck to you.
