I don't know the answer. But I don't think we should judge if we have worth by anyone else's opinions either. I think even the smallest creatures have worth. Even so called stupid or mentally handicapped people have worth. You and everyone is here for a reason. If we can't find it in ourselves we can't love anyone else either. I didn't and still don't see hardly anyone in my life saying I have value to them. I see a selfish and insane society that is driven by material longings (of course not EVERY HUMAN,) but I think it's up to ourselves to find and do things by ourselves to find our values and what we are here for.
