A common meditative practice is to think your anxious thoughts on purpose: What are they? What images to they provoke? What’s the narrative? How does it feel in your body? Notice it all.
Then notice that these are only appearances in consciousness. This is key, because once you realize your thoughts, images, narratives, and feelings are not actually yours, you’re okay. They’re just there, belonging to no one in particular.
This is a practice, of course. You would not expect to squat 400 pounds if you only go to the gym once a week and squat the bar.
