If someone in your life makes you unhappy more than they make you happy, it doesn't matter how much you love them, you must let them go. Not because you no longer care, but because you are finally putting your own needs and happiness first.
Your happiness starts with YOU - not with your relationships, not with your job, not with your money, but WITH YOU. It is not always easy to find happiness in ourselves, but it is always impossible to find it elsewhere. Remember, it is not selfish to love yourself, take care of yourself and to make yourself a priority. It’s necessary. -Mandy Hale
Our greatest happiness does not depend on the condition of life in which chance has placed us, but is always the result of a good conscience, good health, occupation, and freedom in all just pursuits.
I am determined to be cheerful and happy in whatever situation I may find myself. For I have learned that the greater part of our misery or unhappiness is determined not by our circumstance but by our disposition. -Martha Washington
