Child and adolescent mental health services are under increasing pressure as more cuts come their way.
NHS England revealed a cut of around £50m would be made in a parliamentary answer.
A Sussex children’s nurse who wishes to remain anonymous said: “In terms of children and adolescent care I think the 6% cut will affect us in Sussex.”
The government acknowledges that children's mental heath services often lose out when it comes to taking a local share of funding, but they say they will be investing £150m into services for young people with self-harming and eating disorders.
In November, a 16-year-old girl from Devon spent two whole nights in a police cell because there weren’t any psychiatric beds available.
The cuts by the NHS in England come on top of reduced spending by councils.
