There is a different purpose of life for everybody. Everybody is born for different purpose. Some may be born for being doctor, engineer, or singer, actor, what so ever to make the world a great place. People have to find out what they are born for. If you can't find it, suicide. You can think what to do in next birth then. This was said by some Indian guru.
Life is too short for us to dwell on sadness. cheer up and live life to the fullest.
