I always find that when you are having he worst day, just seeing your friends or talkng to them can make the day brighter again. When I'm having a horrible day I usally call my frinds and invite them over, or just talk to them for half an hour, or till my mom gets fed up with me hogging the phone. And it always seems to put a smile on my face. But if you can't talk to your friends, you should pray. Talking to God and telling him your troubles makes them disapear, because he will take all your pain away if you juct ask him to.
