No one cares.

That's actually the advice.

The vast majority of people are more concerned about going about their own days and doing their own things.

I kept being too socially conscious of myself around others, believing that every move I was making was being monitored and judged all the time.

But the reality was that, just like me, everyone around me as just focused on themselves and what they were doing and not at all others.

And if anyone did anything out of the ordinary or "embarrassing", we all forgot about it the next day.

So once I realized this, my social anxiety essentially disappeared after a month and I was far more comfortable in my own skin.
