We all need somebody to love

Is there really anyone in the world who doesn't want to be loved? And not just platonically, either. Why do we all have so much at stake in loving someone, and being loved in return? And why is it so hard to make it work? Knowing that we were once loved isn't enough, either. Please, God, let this work out for all of us. I know you wouldn't have made us this way without reason, so please help us figure this out.
