Questions

I have a few questions.....
Why are some people fortunate enough to find love, and others are not? Why are some of us doomed to walk this world alone and incomplete? Is it something we have done? Is this our punishment? Have we done an unforgivable wrong in a past life that keeps us from happiness in this one? What will it take for us to be redeemed? How can we kill this infection called loneliness, this disease of being unloved? How long will this punishment last? Forever? Until we learn some lesson? How will we know? What have we done? What is our fate now?
