Fortunately, I have had an on and off mindfulness meditation practice for many years. I never want to do it but am always glad when I do. Today I did 10 minutes and it flew by. I find it really helps to label what kind of thoughts come up: "There's a thought about my pain." There's a thought about the past." There's a worried thought" and I imagine them like thought bubbles that drift off into the sky and come back to focusing on my breath. Generally, I barely track one inhale before there's another thought but simply labeling the thought and then letting it float away really helps. I've also been an avid journaler for most of my adult life so I feel fortunate that digging in and writing about issues is nothing but helpful, not stressful or upsetting at all. I'm grateful.
