Even if you are down and weary, remember to always protect your mind. The thoughts that you think can make you or break you. Every time your mind thinks of something negative that makes you vulnerable, your brain cells begin to fire negative energy that can make your mind very unhealthy.  So, do yourself a favor, stand up for yourself and think positive thoughts. I know that it may sound easier said than done, but every time you re-route your mind to thinking positive, you become less vulnerable to emotions such as anger, depression, disappointments, etc... Try it. It works!
