"Worrying does not take away tomorrow's troubles, it takes away today's peace."
When all seems like it couldn't get worse, relax and know that this will only make you stronger and no matter what happens at least you have the knowledge of knowing that you can be better and be happier and make a change.
"Even the darkest night will end, and the sun will rise."
Laugh at yourself, smile, do what you love. Look at the beauty in objects around you and the places around you and find beauty and inspiration in them. Do what you love and find a down time in that and turn to it when you get upset.
