Honestly...likely yes. The vast majority of people seem to only make me feel worse about myself, and that includes both online and in real life. Real life people are terrible enough with their judgemental stares and all; but I've actually found people online to be much, much worse. Like people in real life can call you an idiot in passing, but a lot of insane people online will write several paragraphs about how much they hate you, how dumb you are, and why you should kill yourself. I would argue people online traumatized me even more than real life people.
So even online I barely post or comment on things. Sometimes when I do post or comment I immediately regret as soon as someone throws their first insult at me.
All this to say I isolate both in real life and even online...lol.
