Just turned 23 and feel like I don’t belong

I’ll keep this short.

I started CC spring 2022 and im about to graduate and hope to transfer to a 4-year.

I feel out of place in my group projects when my classmates say they’re 18-20 years old, and then they say, “you’re 23” with a somewhat surprised expression. This makes me feel behind.

Many friends of mine have already graduated or have got certified in a trade, and im still working my part time job, and barely going to graduate CC.

I wish I could just graduate in the blink of an eye, but it doesn’t work like that.

Has anyone felt this way? What do you 18-20 year olds think when you hear this from a classmate? Honestly.
