What should I do if I can't sit still long enough to meditate because of anxiety?

Don’t sit still. Walking meditation, standing meditation, gentle stretching with breath awareness — all count. The idea that meditation requires sitting motionless is a barrier that stops anxious people from practicing. Start with 2 minutes. Move if you need to. Keep your eyes open if closing them increases anxiety. Hold something textured for grounding. Meditation meets you where you are — if where you are is pacing the room at 2am, that’s a valid starting point.
