Meditation helped me a lot. You can train yourself to notice when your mind is doing something unpleasant or unproductive. When you notice that, it typically just stops, and you wonder why you were even doing it in the first place. I'd recommend (ironically) an app for that, but the important part is that you practice every day, even if only for a few minutes. Alternatively, being too busy and/or social to spend any time thinking — I joked the other day that I had "backdoored" my way into enlightenment by simply having no time/energy to think. I didnt create that situation on purpose, both aspects are due to poverty (working two jobs and living in shared accomodations) but they've both had powerful unexpected benefits, to the point where I'm not much looking forward to getting my own place and going back to being alone all the time again.
