Jesus Christ.
Whatever happens in your life, and whoever you meet - there isn't a more fulfilling and long-lasting relationship than the one you can have with God.
He will guide you, protect you, and love you unconditionally - and all you've got to do is seek him.
I know this is something people talk about quite a lot, but finding religion is about "doing" and not "talking". I mean, I found Jesus, and look how happy I am!
