Negatives of life.

What is our purpose here on earth? What are we meant for? It's almost as if none of us can belong. None of us can really be complete. So i don't understand the concept of living to die. Why are we brought here? Maybe it's to find happiness, but why is there pain first. They say life teaches you. and i guess it has.. it's taught me that everyone dies with or without their own consents. And that love brings suffering and change. Why look for time to heal, when time was what brought the loss? time is what killed. time is what cried. time is what changed. So time is bull shit. Life is bull shit.
