I was thinking about it, and I find the only thing that helps me is what I can only describe as the opposite of mindfulness. I pretty much fill my brain with stressless chatter from podcasts. I just don't let my brain decide what i am going to think about and that way it can't take me places that are not helpful. It's clearly not a cure for anything, more like taking an aspirin for a headache, but it is a bit of relief in the moment. I like to listen to light, funny podcasts.
