Just a helpful all-around tip I wanted to throw out here. If you or anyone you know has a crippling addiction to YouTube and/or YouTube Shorts. I found that the best way to break it is not to uninstall the app or block the site (you'll just go to the website or unblock it)
Instead, Turn Off Your Watch History. YouTube Shorts doesn't work outside your existing subscriptions, so you won't be constantly fed a bunch of new content. YouTube's Home page also stops working if you turn off your watch history.
So basically, you stick with your Subscriptions and the sidebar, which shows similar content tailored to the video you are watching, not you. I've also cut down on my subscriptions over time to further reduce my pool of endless content.
I figured this out for myself a few years ago, but I saw PewDiePie post a video about this somewhat recently. His method is more complicated and probably a stronger fix. But my method is an easy start. Just a checkmark setting.
I don't know if this works on TikTok or other apps, but turning off your watch history could be a good start. Don't let the algorithm learn what hooks you... unless you want that.
Take care, and I wish you the best.
