I want to publish my own commemorative book someday...

My dear ladies, good day to you all🌹 A few years ago, I created a fan-made collaborative anthology (novel) with a few friends. It was for a certain free (horror) game, and the original author kindly drew the cover art for us... Although I only contributed two pieces due to work commitments, I participated with a remake and a new story. (I whined until the very end, saying, 'I won't let it be published in print!' but I eventually relented.) Since there are many works by my friends, it turned out to be a thick, yet thin book, much like something by Natsuhiko Kyogoku. However... I will never participate in a collaborative project again... (I only have memories of constant trouble and hardship.) I want to create my own short story commemorative book!✨ (I wish I had a computer just for work.)
