Journaling. Ugh. You're not wrong and I don't doubt that it helps, but to most of us it just seems like more work.
I find journaling a bit like physical exercise: It feels like _work_ in the moment, but you never regret writing it after. And you feel a lot better - there's a therapeutic effect to it. There's studies on this.
And dumping it out by journaling is much better than letting bad thoughts swirl in your head, which leads to even more rumination.
It doesn't mean it's not worth doing, but it is an effort, yet another thing to add to the pile.
This is the fundamental shift - accepting everything including meta. People tend to distance from themselves, as if they were two distinct parts, one broken and one debugging. But the debugging part is also broken.
