You’re only Crying because of Isolating yourself from others
People can also be isolated by being othered by society, e.g. for being neurodiverse, and/or queer, and/or being labelled as an immigrant.
Being isolated is not solely something people do to themselves. It is also a process which people do to each other, because it is not uncommon for people to gain status by reducing the status of others, and thus winning out by comparison.
