i am diagnosed with schizoaffective disorder and also an introvert.I always thought that i was unable to make friends,even my big 5 scores said the same thing. (I think its the opposite,i just became what i said)Until i quit my smartphone and bought a dumbphone instead,for browsing the internet I use my tablet and pc,and it literally changed my life.I really started to talk to my parents and sibling way more and it literally made my depression go away.I remember my therapist advising me that you should socialize more.But I got offended and said why being an introvert is a crime. Turns out I was wrong, theres a big difference between soltitude and loneliness.

Also i guess most people you see on the internet are not actually evil or sadistic.i think its the fact that they cant think for themselves.They are just conforming to a trends and traditions without questioning it,and unfortunately trolling is a trend nowadays.They are doing it just for fun,they are conforming I am pretty sure its not out of sadism,such people are really rare,theres no way so many 12 year olds suddenly starts to be rude to people online.
