I wish you the best. I hope this turns out to be nothing.

Here's some good advice I've been given over the years:
All men die, but not all men truly live.

Don't worry about how or when you're going to die; worry about how you're going to live.

This next one may be a bit morbid, but I like it:
Live in fear of death, for a life lived in fear of death is a life of reflection and repentance.
