I'm feeling this deep and incomplete breathing at random times during the day, and then I get shortness of breath when exercising. A few months back, I was even coughing up blood for about 34 days, and had something similar happen a year ago. On top of that, I'm having these gastro issues like thick and sticky mucus in my stool every 10 to 20 days. I've lost a bunch of weight, dropping to 79 kg over the past 3 years, and I feel like my growth has stopped. Do you have any idea what's going on with me?
