Someone once asked...
Someone answered with kindness...
I don't think there's a way to shut off your brain. You might be able to move away from one specific thing you're stuck on to other hundreds of things. If it is sleep that you seek I found a method I saw in the series mentalist to be quite helpful. So the method is that when you go to sleep when you close your eyes breath in counting one and breath out counting two. That's it. Just focus on that only. Don't think of anything else. If you feel your mind wandering bring it back to the breathing. It helped me fall asleep in 10 mins. I hope it helps you too
