A heartbroken mum has paid tribute to her "lovely" who unexpectedly died in his sleep just after finishing his A-Levels.
John Nesbitt, 18, was looking forward to studying mechanical engineering at The University of Birmingham when he died suddenly in his sleep from a rare heart condition that didn't show any signs or symptoms.
John's heart stopped beating as a result of an arrhythmia caused by myocarditis - a condition where the body's immune system causes inflammation in response to an infection.
