"When I returned to the UK, my worst nightmare came true."
In 1996, Billy served in the Royal Artillery. He was posted to Bosnia on a peacekeeping mission, which included the horrific exhumation of mass graves. Billy contracted a rare virus as a result.
He woke up one morning and opened both of his eyes to pitch black. He was completely blind.
Billy's whole world collapsed.
That's when Blind Veterans UK stepped in.
