Why do I randomly have shortness of breath?

Why do I feel shortness of breath?

• I am about to be 18 years old and I am relatively in good shape. I eat right but i haven't lifted weights in half a year and i haven't done cardio exercises in almost two months. Today I worked on my chest on back and I felt a shortness of breath midway through the workout out and about half an hour after I was finished and sometimes even throughout the day. I was used to doing high level intensity cardio and had a good cardio. Could it be that I have lost my cardio capability so i get tired quicker which is why I have this shortness of breath?I think I am also dealing anxiety/stress. Or what could it be? Thanks -David
