Look at this as an opportunity, not as a failure. An opportunity to DO something you want to do. An opportunity to live. Yes, it is an opportunity to pour everything you have into helping yourself be happy. Learn from the past... become a better person because of your mistakes. Live for yourself.
Find out about yourself. No one else can make you happy without your permission. Give yourself permission to be happy. A chapter in your life has closed... A new one is opening. Look ahead, don't dwell on what's behind. Live and learn. Nobody is perfect.
Hey... quit beating yourself up, here... you know?
