Pico8 carts are just a special flavor of png. I would try running it directly or if it won’t run them with the png extension just rename the file from .png -> .p8 without converting and see if that works

There are three ways to share carts made in PICO-8:
1. Share the .p8 or .p8.png file directly with other PICO-8 users
Type FOLDER to open the current folder in your host operating system.
Although if you are having trouble you might have more luck getting started with the built in SPLORE command

This might be easier to get started with since it will all get wired up automatically for you
You sound a lot like me. I figured it out for myself, maybe this insight will help you, maybe it won’t apply, but I’ll share.
I’m an introvert to start and on the spectrum. The world seems built for extroverts, and for a long time I thought the thing I was “supposed” to do was a bunch of extrovert activities that required me to mask my autism and drained me of all my energy. I felt a very similar feeling of being with people but feeling alone, I was in my head carefully running the scripts and behaviors I have learned. Not consciously (well, sometimes consciously) but it was just this extra burden I was carrying around that no one else was. It wasn’t a fun day at the beach without a care in the world, it was an assault on my senses, everything is too bright and too loud and sand is everywhere and “oh, what did that person just say, ugh, I don’t know what I’m supposed to do in this situation. I don’t want to play volleyball but are you supposed to anyways because that’s what people do at the beach?”
Over time I found people whose interests more closely aligned with mine. People I could trust to share my true self with, and not the mask of social scripts that I had learned was what I was “supposed” to do. And I realized I was not alone, but that a lot of the activities that people commonly associated with social togetherness were just not for me.
University can be a difficult time, most of the fun to be had is in those activities that I wasn’t very compatible with. I used to think that maybe I was broken too, but now I think that I am just different, and there’s nothing wrong with different. I have friends and a wife and people that I care about and who care about me, the real me, and I don’t feel so alone anymore.
I wish the same for you, if you like exploring the city with headphones, find someone that wants to do that too. If you like watching a dog play with a ball, there are people that will want to do that with you too. I found the more I opened up to people about who I really am and stopped caring about who I was “supposed” to be, the happier I became, the less lonely I felt.
I am sorry things are difficult for you now, in my experience it does get better. Early 20s are the time when people want to party and go to concerts and be quite loud. In a decade those same people will enjoy a quiet evening at home just as much as you do now.
You my Internet friend are not broken, you are just different, and different is beautiful.
