When you exercise, your body releases chemicals called endorphins. They interact with the receptors in your brain that reduce the perception of pain. Endorphins trigger a positive feeling in the body, similar to that of morphine. Research shows that exercise is an effective but underused treatment for mild to moderate depression.
When someone treats you like you’re just one of many options, help them narrow their choice by removing yourself from the equation. Sometimes you have to try not to care, no matter how much you do. Because sometimes you can mean almost nothing to someone who means so much to you. It’s not pride – it’s self-respect. - via: http://www.marcandangel.com/2012/05/23/14-rules-for-being-you/
