Everyone just wants to be accepted, understood and be a part of a group to take part in the reciprocation of giving and receiving.
If any of those feel broken or missing, a person can feel rejected, misunderstood, alone and worthless with nothing to offer or give.
A person like this might feel like an outcast, broken and as a reflection reject society. The perception of being rejected by society may infiltrate their thoughts to the point where they conform to that external perception and now see themselves as “rejected” – hence they’ve closed the loop and are now creating an internal perception of rejecting themselves.
They are now in the loop of being rejected by society, externally and rejecting themselves, internally.
