That sounds serious! Need detailed medical history.

Go to your doctor. Your shortness of breath can be due to inadequate oxygen getting into your blood. This is a function of gas exchange. It might be manageable by increasing your oxygen, but you should check with your doctor first. Sometimes increasing the oxygen can actually make you breathe in and out less, resulting in the retention of carbon dioxide - which is bad. Good luck and feel free to ask more.
