Not sure what religion really is and what is the true religion.
The key to all religion is faith and to have faith is to believe. When you believe you draw strength. Believe in yourself and draw strength to continue in life. If you can't draw strength within yourself then draw strength from good friends, family, or even your children find a reason to live. Some people will believe in a better afterlife and they do good in this world and hold their smile. You don't have to believe in a god and worship an omnipotent being just believe in yourself, just believe in something, just believe in someone more than yourself.
