Easier said than done but definitely worth remembering to try.Incredible change happens in your life when you decide to take control of what you do have power over instead of craving control over what you don't.
I think you are finally able to move forward when you can look back and accept the past, realizing there are no mistakes, no regrets just moments in life that changed you, making you a better version of yourself!
"Negative people need drama like it was oxygen--Stay positive and take their breath away." I wish some people would grow up, get over themselves and move on! Make a life for yourself, be happy not jealous or malicious.
