Scientology will see them through.
As someone who has come close to losing a child, I can tell you that you have to work hard at not completely losing it. I am a practicing and pretty serious Christian...and that did not help for a while.
Let go and let God became a pretty common mantra for me.
At that point in a persons life, faith is tested seriously. And, if your faith—no matter what it is—helps you through it, then go for it.
