The actor and his wife Kelly Preston were devastated when the 16 year old died suddenly after suffering a seizure during a family holiday in the Bahamas last January (09).
And the Pulp Fiction star, who is a longtime member of the Scientology community, admits he has relied heavily on his faith to help him heal.
He tells the Associated Press, "We work hard every day with our church on healing. And Kelly and I and (our daughter) Ella have all been working very hard and they've been helping us."
Travolta insists it was Scientology which helped him return to the spotlight, adding, "Once you get yourself stable, then you're able to reach out again, you know, and I think this whole year every day we've been working on stabilising ourselves and it's been successful so far."
