Update:
Went to the cardiologist today to test my heart. It's in good condition thankfully. Still no clue as to how I'm having such severe breathing problems.
I went to draw blood for my DNA test as well today. Had a good look at the order for the test and the doctor checked the "confirm diagnosis" box as a reason for the test. :hat
I also got to see what the suspected diagnosis they're testing for. The order said CPT II
