hello i'm 16 my weight: 95 KG (i know it's alot ) i have had this problem for at least 5 years whenever i hear/watch something that reminds me of breathing .. i can't breath ,,it lasts for 1-4 minutes ,, it also happens when i go to the sea (which doesn't happen much coz i'm afraid to drown and i have no idea how to swim ) or watch someone drowning on a movie i went to see a doctor (i just told her that i can't breath ) she ran tests and told me that i'm all good if it helps i think i have social anxiety and maybe that's what's causing it
