Hello Lorenzo,
Welcome to the forum. I am going to assume your comment about jumping from a building was just a figure of speech and not meant literally.
You did not say when you had your ASD however I guess that does not matter as it is the SOB that is your main concern. I agree with Kate, do make that appointment and get a medical screening exam to investigate the cause of your SOB.
I understand your anxiety and how hard it is to deal with the SOB as it is truly a scary feeling when you cannot get enough oxygen into your lungs.
Keep talking with us and remember that ERs are available for breathing problems so if you feel you need to be seen sooner do go to the ER.
Kindly,
Kitt
