Calling her and asking how she is won't help you, I can't only speak from experience there though. Obviously I, nor anyone else knows you and can't possible know what ringing her would do to your but I doubt it will make you feel better. As I said originally I though it was loneliness which, is awful especially when you've not been lonely all your life. People saying getting drunk doesn't help, technically it doesn't although it does help you fall asleep before your head has hit the pillow.
