my mother’s cry for help

Hello :)

My name is Mathilda, i am 15 years old and I come from Sweden. I am not the one who is in the need of the money, it's my mother who is. 1 year has passed since she divorced from her man/my father. It was not a simple divorce, since he was/is a drugdealer and have been his whole life. My mom wanted him to stop using for me... but he didn't want that. That have destroyed so much and have taken so much happiness out of life. Her wish was to start over with me. But, before the divorce he gave her a payment default which have really destroyed so many things for us and her life. She can't borrow money from the bank or anything... She has her own little coffeeshop in a small town in Sweden, we live by the summer guests that come here. The autumn/winter is hard, we can't pay our bills or the apartment bill. If we can't pay it.. it means i have to move back to my father, who's using drugs on a daily basis. I'm afraid and i don't want that. Please please please help.
