Cold, scary and tiring was how Hayley described her night sleeping on the streets of London.
Armed only with the clothes she was wearing and a sleeping bag Hayley set off on a mission to find out what it was really like to be homeless in the UK today.
The charity Centrepoint says there are over 80,000 youngsters currently living on Britain's streets.
