Sarah and her mum had to leave their home because her mum's boyfriend was very violent to them.
He was always swearing, slamming doors and throwing things around the house, smashing them and scaring Sarah.
He also bullied them, taking Sarah's dinner money, and anything her mum had.
"My mum just gave in to him," she told Newsround's Becky Jago. "She had been through so much, she was just weak."
Safe place to go
Things got so bad the pair had to leave their home - but they needed somewhere safe to go to.
This is where the shelter comes in.
