Scary Coughing Fit and Couldn't Breathe?

maybe asthma? i have it really bad and when i have bronch it makes it a million times worse i cough alot n can barely breath, ive been to the hospital twice for it and last time they said if i woulda waited any long i would had a heart attack because of the pressure being put on the heart, i was gasping for air n coughing really bad, you should go to your dr. and get checked for it just in case
