Everyone goes through a tough time in their lives, which don't allow them to be happy.  But we shouldn't always look at the bad that has happened, but look at the good that should be coming our way.  There is always a ray of sunshine at the end of every rainbow, and although we may not realize it our world and our lives will not always be of pitch darkness.  If you have someone or something to help you with your goals keep up with your dreams and everything would come shinning your way.
