First, you need to calm your physical body down. Ground yourself. Do this in physical ways. Eat potatoes, rice; if you're a meat eater, eat a steak also; if not, root vegetables, lentils, are good. My go to is potatoes. Drink a lot of water, Have showers or if you have a bath lay in a warm salty bath for a long time. Table salt will do but sea salt is better. Breathe. In through the nose and then slowly out through the mouth making a wooshing sound with your lips. This breath will - it may take a few days - calm your nervous system down.
Try and leave all the esoteric and sensing stuff alone till this all calms down. Then you can review.
Watch dumb comedies. Go for walks, preferably with trees around you, a park, or just suburban streets. Keep doing the slow long breath out and try not to think about the pressure in your body but give your heart centre a soothing rub now and then. If you have a heat pack lay it on your solar plexus and hug it against your chest. Whatever you can do that you know relaxes your mind and body, do. Jigsaws, computer games, looking at picture of fluffy animals or roses? I don't know, but do it.
My chest is spasming writing this! Good luck with it all. It's a horrible state to be in. Ground yourself, young man! You can do some light visualising of unwanted energy leaving your system as you walk, say. Stomp it out into the earth. Sit with your bum on a rock or the grass, etc, and let earth take it, But I would stay out of the energy arena for a bit when things are this extreme.
