Someone said bad words to you on the internet? Close your browser tab: you're done. Learn that you can't please everyone and you're better alone than with bad company.
I don't know if it's because a lot of drama queens and marketing people populate social media but it feels like most people can't fucking live without the approval of everyone when reading some websites.
If you want to bring conference in (it's IRL, can't close a tab) here is how to react: when someone start telling you shit, stop speaking, turn 180°, go join another group of people. It's rude? So what? Some person is now fuming while you're stress-free and engaging with better people.
Learn to ignore people. Learn to say no. You don't have to please anyone.
Usually "treat others like you'd like to be treated" is a good heuristic. If not I'd encourage you to seek a therapist and start working on yourself.
