I Worry About the Future For Myself

Today I went out to eat with family and as we were eating I happened to see someone getting up from their seat on the from my prepherial vision, I then focused in and realized it was a fellow old classmate of mine (Aka a someone I used to have a little crush on...) I saw them get up and leave and go to their car and drive away...and I just kinda stood there thinking "Wow everybody's old now" but not just that (yes I'll admit I think there still pretty damn cute/hot, but that's not what I'm talking about arm) I just sat and thought how mature they seemed you know, how them driving here and coming to have a meal here is a norm, and their pretty much an adult now. I just thought "If only that were me" because i just feel stuck in a way...sure you could say "But your as old as they are, why are you saying this?" It doesn't have to do with numbers with me, it has to do with being capable of being able to do things myself or independently. I feel this because I am me, and I'm just some lazy, anxious person who plays things off and does not plan/prepare for my future. And I know I'm comparing myself I get it but at times I can't help but do so, because aquientences or people I know at that I see on the streets or outside, sometimes they are who I wish I was or could be....
