For me, it was switching to Lemmy as my exclusive source of social media. On reddit you could doomscroll all day and barely scratch the surface of available content. On Lemmy you've got like an hour max before you run into yesterday's posts. It's like quitting smoking by switching to nicotine gum.
It also helped that reddit is run by absolute scumbags and I was part of the exodus during the API-pocalypse. Not using reddit became a moral stance, and I'm far less compromising of my principles than my vices.
Maybe this is a bit more of my personal situation than your problem, but I have wicked social anxiety. I was on reddit for ten years and left maybe five comments. The community on the fediverse is so much smaller that it feels easier to get into and form a more meaningful connection. People seem to be friendlier, and while you do run into the odd person who's violently intractable, their population is also much smaller than reddit.
And to further bash reddit and mainstream social media: the bot users, the doctored algorithms, sponsored content, and relentless advertising - they're all extremely manipulative and show no respect for you as a human being. We all deserve better than that.
You aren't pathetic Little Mouse. You're a little mouse and you're dealing with big shit - the weight of the world is crushing. If I may, I'd advise you to stop chasing the perfect content and learn to appreciate and contribute to what you already have. Way easier said than done, but it's said with love
