In times like that, you can only count on yourself. You have yourself.
Try forgetting about your boyfriend. I am strongly suggesting about not getting into another relationship. Do not count on people to make your life better. You have to do it.
The only advice I can give you right now is stay strong. I have a friend in Russia who is 16, same age as me, has 3 little brothers to take care of, and is without a home or parents.
Believe in yourself, and stay strong.
Best of luck.
