Don't stress about the bad stuff. Your current problems. They will go away. You'll work through them. You always have and you always will.
The good stuff. Your spouse. Your family. Your friends. These things don't go away and they're good for you :)
FOCUS ON THOSE.
A year from now, you'll be laughing about whatever is challenging you today. And chances are you'll be laughing about it with the "good stuff."
