As part of our week-long series on homelessness, Hayley travelled to the North East of England to meet one young man who until very recently was living on the streets.
Liam who is 18 and from Sunderland became homeless when things became too tough to carry on living at home.
Hayley hears how finding a bed for the night and food to eat became a daily struggle for the teenager.
Liam says being homeless was a shock.
He talks about finding shelter from the cold and rain and sometimes surviving without food for three or four days.
Things are now looking brighter for Liam because he's getting help to look for a job and somewhere to live thanks to a local hostel.
Watch the film to find out more about Liam's story of life on the streets.
