Forced to live with my Crush?

Hi my name is Katerina Smit. My dad died when I was 2, so I never really knew him. My mom is the only thing I have. I have my sister to but there's not much she can do. My mom has been through many abusive relationships since my dads death. Just 3 months ago my mom decided we should move to another city , new schools, to restart our life. I loved my mom, she was the only thing I had, so I trusted her that it was a good idea. The city we moved to had a ton of my moms old friends, and really good friends if you ask me. My mom and I didn't have any family left so it was a good idea to move towards great 'family' friends. One day during moving my mom was hit by a truck. I was crushed, broke, so I resorted to cutting as my get away. Since I was fifteen, I couldn't raise my 5 year old sister and stay home, the court said I had to find someone to take us in or we would be put in a foster home. I didn't ask this woman but she immediately took us in, of course I knew her, it was my moms best friend. It wasn't her I was uncomfortable living with, it was her 3 younger daughters, and mainly his 15 year old son.
