Life is constant struggle to belong and cope
When you come to a point in life when you realise life was nothing but a constant struggle to belong somewhere, a community, a family, those who have a family, maybe all of the family including myself going through mental issues, or have certain rigid moral values, then you observe yourself or your family slowly gradually being faded out, ostracised eventually being made to forget you are human being. Life is a constant struggle so that your community doesn't dehumanise you, because once they do, and you can't afford to shift from there, then you die a slow death, a cruel one, nobody will bat an eyelid if you or anyone or your family doesn't exist, dehumanizing a human being is one of the worst thing that a human can face, but that's it. Life is that struggle where you try to cope up with that pain for that long, till you can't, then nobody will care,
