I've never choked before, but I've had a pretty severe laryngospasm. It was the scariest thing ever, it's a cramp in vocal folds, cutting off all air supply. Basically my body was choking itself. It was terrifying!! I could only stand there trying to gasp for air, but not being able to... not even being able to for help. I remember feeling light headed, faint and my vision started bluring as I tried gasping for air. I was convinced I was going to die.. eventually the cramp let go and I was able to gasp and cough like crazy.. I have no idea how long it lasted, but it felt like forever. I saw my life flash through my eyes. It really is terrifying not being able to breathe
