As a highly sensitive, highly empathetic person who had a very sheltered upbringing, the biggest challenge I've faced in adult life has been coming to terms with how much shittier people can be than what I thought growing up. I wish my sensibilities had been calibrated at a much earlier age based on the actual spectrum of good and evil that exist in the world.
The video I've linked to will probably scar you and you might not be same afterwards. Hopefully the scar becomes an emotional callus that helps prevent pain down the road.
