John Travolta has said that the death of his teenage son Jett was the worst thing that has ever happened in his life.

The 'Pulp Fiction' star said that he wasn't sure if he was going to make it after his 16-year-old son passed away and life no longer appeared interesting to him, the BBC reported.

Travolta added that it took a lot to get himself better and the Church of Scientology had been pivotal to his recovery in the weeks and months afterwards.

Jett Travolta died at the age of 16 in January 2009 from a seizure during his family holiday in the Bahamas.
