one thing to consider your past wasnt all that great by dwelling on it your like reliving it all over again. No ones abusing you in this moment thats done and gone. But if you dwell on it your basicly putting yourself through it over and over again. I know the drill keep rehashing it over and over and over hopeing to conjur up a different or better outcome when there isnt one. Things just are just let them be. Leave them.... in the past where they are and you are not.
