Laughter is the best medicine. I always make myself laugh.
Tomorrow is a new day. The sun is going to come up. A bird is going to find a worm or bug to eat. Just be glad your not a bug. ~ Anna Disch

There’s always some reason to be positive 
Believe what your heart tells you 
Inhale, Exhale! Everything is going to be okay 
As long as the relationship lives in the heart
