I'm not sure if this helps or makes it worse, but most of the time when I see r/AITA referred to in other subreddits, the consensus is that most of the stories are made up and all use the same kind of beats, all for the sake of karma-farming.

I hear you though, because I went through a phase of also reading that particular subreddit a year or two ago, mostly because I found the replies useful to take into account perspectives I may not have considered... but it's all a lot, and the initial stories can be so depressing or anxiety-inducing.

Good on you for stopping when you noticed it didn't bring any joy any more!! Hope you find something more fun to do with the time :)
