Stack stones, hang lights, collect interesting things. Or join a project where people are doing this, like Sandland: https://www.southeastiowaunion.com/life/ottumwa-native-creat...
Joining may be easier and nobody turns down a volunteer. You may have to start something new if nothing is nearby.
But beware the monkey’s paw: once the people come, you will not be able to get rid of them easily.
I actually grow up in a small town, like 4000 people in total, in Italy. It is even worse: if you're just a little bit strange and you don't form some kind of friendship while in grade school, the rest of your social life is basically determined to be over.
Second, it's weird that what you've written comes off as entirely insincere. It's like you've been assigned a high school essay to "write what a sad person sounds like."
You aren't even really talking to me at all. It's a story you're telling yourself that is actually deeply self-absorbed, maudlin, and also clearly false. I don't think you find your life pleasant, but I believe there is something you are not telling me, or yourself, about why that is. Good luck figuring that out. I don't know you at all, but I think you're capable of it.
I can understand being in the wrong contest once or twice in your life, but I’ve lived in five different cities. I’ve gone to college three times. I play multiple instruments and have played in bands and orchestras. And yet here I am: completely alone. I have no one to text for a little chat, no one to grab a beer with me on a Saturday night, no one to plan a coffee with, no one to reassure me when I’m struggling. I’m moving through life entirely on my own, rawdogging it, doing everything alone.
At this point, I’ve given up on relationships, on friendship, on love. The few people I’ve ever called friends eventually disappeared. It feels less painful to stop hoping altogether than to keep sinking my already low hope that it is actually all a misunderstanding and that someday I’ll finally find a circle of people who choose me back.
