"Thank you for changing my life" - the touching letter from a young woman to her foster carer
If ever you want to see an example of how fostering can work - this story could move you to tears.
It's the story of the close bond that grew between a foster carer in Lancashire - and the young woman who she and her family looked after.
Marcia O'Connor became a foster carer in 2012, opening up her home in Haslingden to create a safe place for vulnerable young people.
And Yana who's now 18, wanted to say thank you.
