Life is too short to wake up in the morning with regrets. So love the people who treat you right, forget about the ones who don't and believe that everything happens for a reason. If you get a chance, take it. If it changes your life, let it. Nobody said that it'd be easy, they just promised it would be worth it.
When I get hurt or angry some need to understand that I'm human just like them and will do things to try to hurt back and lash out. I don't want to but we all tend to. especially if our emotions are played upon and we are despitefully used and manipulated.
