Let things go that you can never change. Let the sunshine in and have a happy life.
We are all so different from one another. For some adjusting to changes and letting go as well as accepting rejection is almost impossible to do. Coping skills, detachment skills, self love are things to learn. Not every one can afford mental / behavioral health care, people just live hidden sad lives. Very sad when it happens to people you love. ~ Lea Gabbard
Let go of the people who dull your spirit 
No matter how much it hurts now 
When something goes wrong in your life 
Never drop down to someone who treats you badly
