I found the one I was looking for and it was removed because the guy closed his account! I looked for others and couldn't find anything like it. His basic message was to not fear the attack. This helps because a person's reaction to the attack makes it much worse. He was really calm in the video and he was saying "Okay, I'm having an attack. I'm going to be okay. I always end up okay after an attack." He advised not to fight it and to not berate yourself because you were having it. Breathe and try to calm down but don't make it worse with fear and dread.
