@LukeAlmighty I felt old af in high school because I was going through a lot of shit. I don't have nearly the same stress on me now at 27/28.
I have periods of feeling old still, but for the most part I still feel really young. I can hang out with a crowd of high schoolers and relate to them despite being 10 years older and in a different generation. One of my coworkers finds it really weird how well we get along xD
Part of it might be because I'm a bit stunted from my epilepsy. I can't do as much adulting as other adults do. I've mostly accepted that, and I'm very fortunate to be able to do what I love most of the year and get paid for it, otherwise I'd be in a pickle.
I also haven't visibly aged much since high school lol. I've got the beard but if shaved it clean I'd look like perhaps a college freshman xD I'm almost thirty and I have guys only a few years older than me calling me "bud" still xD
