I have panic disorder and stress is not my friend. One way I've been taught to manage it is to follow a progressive muscle relaxation exercise. It takes about 30 minutes, but it does the trick. The particular kind I do involves laying down, closing your eyes, taking a deep breath, and then begin tensing and releasing groups of muscles. I'll lay out the process incase you want to try it, or find your own version somewhere.Make a first with your right hand and push your elbow in against your side. Hold, notice the tension for 6-10 seconds, then release. Tense 80% relax 100%. Give yourself 30 seconds to let the tension go. Do that twice, then do the same with the left arm and hand. Raise your eyebrows next in the same pattern of 10/30 sec twice. Squint your eyes, wrinkle your nose, and pull the corners of your mouth back in a grimace (twice). Raise shoulders to your ears twice. Pull shoulders back like you're standing at attention twice. Tense your stomach twice. Point your toe toward your head and tense your upper leg (each leg twice). And finally curl your toes and point them in toward each other, but for less time as they might cramp. Give yourself time afterwards to feel your body relaxed and daydream a bit. Then take a deep breath and open your eyes.I've fell asleep doing this before. An anxious or stressed mind has trouble existing in a calm body. Hope this gave you some ideas. PM me if you have a question.
