Antisocial sounds negative. But introversion is fine. Those sorts of people can open up to those who matter.
fk yeah, look at me!?
Are you referring to Antisocial Personality Disorder? That's not a disorder anyone wants. The common name for Antisocial Personality Disorder is sociopath.
Because you give off a negative vibe to people that might want to get to know you and worse yet get a reputation.
Its fine. You are not hurting anyone by being antisocial. Its ridiculous to even imagine it being not okay.
It is always ok to be yourself. If you are antisocial, so be it. Faking is worse.
