You don't have to deal with or relive your past, you can just close that chapter of your life. There, done with that!!
Today is the first day of your new life. The life you want to live and the person you want to be has now begun. Go enjoy it, you deserve it.
You and only you, control your perception and attitudes to the people and things around you and to yourself.
With that in mind, go look in a mirror, smile and enjoy the new person you have become and embrace it. You can do or be whatever you chose to be.
Best wishes
