One mistake many people make is that they try to ignore their emotions altogether, which is the worst thing to do. To move forward, feel your emotions. This is key to understanding why you are upset in the first place. Let the tears come until you can cry no more, or scream into a pillow until the frustration ebbs away. Let it all out in order to let go of the past and live a happy life. Read these tips on why it’s ok to cry. However, don’t get lost in the emotion. Make sure you remind yourself that you are not your emotions. Your emotions affect you, but you are in control of how you feel.
