Hey!! I always have to remind myself of this, so I may as well remind everyone else too!
If you’re still embarrassed about something that happened years and years ago, nobody else remembers or cares by now!! The only reason you remember it so well is because you were the one at the center of it, and rehearsing the event in your head and remembering how uncomfortable you were at the time further cements it into your memory, so it’s easy to think that everyone else who was there at the time remembers it as vividly as you do to this day or that it was just as significant event to them as it is to you, but that’s not true! I’m willing to bet $99 that nobody who was there has even thought about it since. None of them care anymore (if they even cared that much to begin with), so there’s nothing to be embarrassed about anymore!
