@kperry set a timer in your house for 10 min and walk. Do this a couple times a day. You can breath- take tiny sips of air in and out and focus on getting stronger. Sometimes putting a liitle esential oil (peppermint or eucalylptus) on a tissue and inhaling that will help you breath. Drink plenty of water. Reach out to your doctor about anxiety meds and think positive. Get a pulse oximeter so you can see your oxygen levels. When we have extra time to foucus on every breath we take it is overwhelming. I'm only saying this from a firmilar place. You will be ok.
