After lurking for a long time I finally worked up the courage to make an account and contribute to the forum. I definitely enjoy contributing but I still find myself constantly second-guessing anything I type and editing it over and over again to make it sound right. It helps that it's anonymous and everyone here is friendly but it can still be hard sometimes.
I definitely feel that. I sometimes delete Youtube accounts to ensure all the comments I've made in the last year or so are gone. I had debilitating social anxiety when I was younger. I'm not so bad now - partly because I realized that 50% of it wasn't anxiety - it was simply my introverted personality. But the part of it that was anxiety caused me to go over everything I'd said to anyone that day, over and over, to see if I'd said anything shameful.
This will probably sound harsh, but the thing that helped my social anxiety more than anything, was the realization that I was being really selfish. I thought I was the centre of the universe, that I was special, that the things I said to people were really important, that people should care what I thought and said and how I said it, that my opinion on this or that was important, and that other people must think my opinions are important too, that other people valued my existence within their lives as much as I valued my existence within their lives. I realized that I was
HUGELY exaggerating how special I was in the grand scheme of things, and how significant my existence was to strangers. I was projecting my own self-centred importance onto how I thought others perceived my role in their lives.
A way of thinking that helped me - to remember that you are the leading role in your own movie, and to your family and friends you have a supporting role, but to everyone else on this planet you are an insignificant extra who won't even be on the end credits - they literally don't give a shit about your role in their movies whatsoever, they don't even know you exist! They're too busy thinking about their own leading roles and in their own movies to give a fuck what you said 10 minutes ago, they weren't even listening. And to top that all off, THEY are just an insignificant extra in YOUR movie, so what the fuck do you care what they think anyway?!
From the Truman Show...
Truman - "...it feels like the whole world revolves around me somehow."
Marlon - "It's a lot of world for one man, Truman. Are you sure that's not wishful thinking?"
Another thing I do that helps a lot is make a list of all the things you would have to do to be a truly awful person by your own standards (yours, not others), things you would have to do to feel genuinely ashamed of yourself socially, so...
Swore at him/her aggressively
Tried to frighten him/her
Threatened to punch him/her
Tried to bully him/her
Tried to intimidate him/her
Tried to purposefully manipulate/deceive him/her to get what I want
Deliberately tried to insult him/her to hurt them
etc...
And when you're feeling anxious about a situation that has happened, go through the list, tick each one off, and now you know you did nothing bad,
by your own standards, which is all that matters to you and your conscience, and then you can forget about it, or go through the list again if it pops up again!
Maybe some of that will help!
