I've never understood people that yearn to be a kid again. When I was a kid, especially when I was in high school, I desperately wanted to get all that over with and become an adult. And when I became an adult, things were rough, but I felt so much better for so many reasons.
As I've aged, this sentiment has only been further reinforced by my experiences with aging. Not to toot my own horn, but I've been aging well and have gotten more attractive the older I get (so far). My social skills have improved so much, I was painfully awkward and unable to successfully socialize as a young person. Holy fuck, I actually have real friends and relationships now, it's amazing. Yeah I got responsibilities, but I can actually do things I want to so long as I stay within the confines of those responsibilities, definitely not something I had as a kid either. And honestly, I'm a much better person, which I won't get into too much, but I was closer to being right wing in my younger days.
Sure, it'll stop feeling so great at some point, but I'm kinda past the point where most people start to say getting old sucks and you know what, I say no, it's pretty cool actually.
My childhood was awful and so was my 20's. I grew up in an abusive, isolating, home, moved onto to abusive friendships, then I transitioned at 28 (ftm) and spent my 30s in heavy therapy/COVID lock down.
I'm forty now and I feel good about it in some ways, upset in others. Because I transitioned later in life (and due to being isolated with agoraphobia for a while) I relate more to people in their 20's due to my lack of male socialization and financial status. I don't relate to most people in my age group, especially the straights. I'm afraid of giving my age due to the stigma (thank God my hormones make me look younger)
After being a meek woman for most of my life, I am still not used to being a big buff man either. Not that I don't enjoy it, but I don't like being picked on by dudes looking for a fight.
On the flip side- I'm way happier overall and because I worked through my demons my relationships with others are much healthier. I let the little things go, and my life is mostly drama free. I am salty I am doing things I should have done 20 years ago, but at least I'm here.
