What can I say? Nothing really, I am numb after reading that, especially when I realised your age......
I am going through a lot at the moment due to my mother in law being terminally ill (she has 3 secondary tumours in her brain) and the best advice I can give is make sure you patch up any bad feelings before you go - those you leave behind will appreciate it even more.
I'm going to hide now and have a good cry, stay strong and I REALLY hope you get out to Italy.
As others have said, if you need ANYTHING just ask.
