@trellg132 – I know that you have asthma. Are you treating this with any medications? It's one of the most scary things to feel that you can't breathe. There are exercises that can help you learn to control your attacks. The most important thing is to breathe through your nose. This also helps warm the air. Take small breaths and take shallow breaths at first so that you can get air into your lungs. I suggest sitting up. Also pull your shoulders back to open your chest. https://www.healthcentral.com/slideshow/7-breathing-exercises-to-control-asthma
Will you try these? Can you look into groups that support asthma patients and support good exercises?
