Any other 20-somethings hate running into people from high school?

It's probably my worst fucking nightmare. It doesn't happen very often to me, but when it does it is immense, soul-sucking torture every time, especially if it's when I'm at work at my retail job.. Maybe it's cause I'm a broke college dropout and I feel kinda like a failure in comparison. Even if I know that most people in our generation are struggling hard. It's still embarrassing and I always feel super awkward. Not to mention the cringe over how much of a goddamn idiot I was in high school. I just try to forget it ever happened. Does anybody else feel a similar way?
