I would also not be seen talking with more than one or two selected people, I would shut down for fear of saying something wrong and then something happened…
After 2 years of working in the sector and being extremely introvert same as you and @JacksonBates describe I was told “go and set up the IDE and projects of the new guys, give them an onboarding”, I was sweating, trembling thinking “oh s**t I have no clue what to even do, what do I say? What will they think if I say something wrong…” panic panic. I sit next to the first person I have to help and I notice no movement, this person in front of me was completely paralyzed with fear (we talked after about this moment, even some years after we remember it in a funny way) and that’s when the click came, we’re all nervous with the same or similar, fears just that some have more confidence either because they’ve been in a certain scenario so much they focus on what they have to do and not on what can go wrong or because they naturally understand that nothing irreversible can happen, if you make a mistake and you notice it just talk about it and people forget quicker than you imagine, it keeps itself in our head longer than on other people’s because they have their own fears and “mistakes” in their head, not yours.
Challenge yourself to do meetups listen, question and then do one yourself, the first presentation I did I blocked in front of 30 or so people multiple times, in the “after party” people were talking about the good points, nobody cared that I stumbled or make a couple of mistakes replying to them, they cared to know more or to teach me more.
If you look at it, by this post you already fought it and look, nothing wrong is coming out of it, people are being cool about it and helping you out, most people read and ignore (or keep silent) and the people who are idiots have usually more problem with themselves than with you so don’t focus on them.
The biggest celebrities do ridiculous stuff all the time, people talk about it for a while and move on to the next ridiculous thing, they forget it ever happened and continue to celebrate that person’s work.
Did I stop sweating and trembling immediately after my story? Heck no, it still took some time to have it not be my default behavior when having to interact, when I publish an article even after reading it and double-triple checking I still sweat with the thought “what if I said the biggest stupidest thing ever? What if I mislead those learning?”, there is an edit button exactly for this
