Is it normal that i'm less insecure around my hs friends than my college ones?

So I graduated from college a few months ago, and the other day I saw some of my high school friends. And it felt really good--I didn't feel like I had to impress them with everything I'd been up to, and it was just a totally comfortable and relaxing experience.

But even though it hasn't even happened yet, I'm dreading the next time I see my college friends, whenever that is. I am doing something in the fall that I've been calling a job for all intents and purposes, but it's not paid and it's only in the mornings. I want to go to grad school eventually, but I haven't even applied while so many other people in my year are already set with that!

Don't get me wrong, I know rationally that I have people in both groups that love me unconditionally. It's just that with my high school friends it's easier to internalize that.
