Harboring animosity towards somebody is like carrying around a backpack full of rocks. You don’t have a problem carrying it, but it is a load on your back, and life sure would be easier if you could just take it off. Do yourself a favor, forgive. This doesn’t mean you need to become best buds with whomever has done you wrong, but come to terms with what has happened and understand that people make mistakes. Forgiving will help free you of anxiety, stress and depression and allow you to have happier relationships. Free yourself of the hate, and MOVE ON.
