Heart attack at 14?

Is that possible, because I think I just had one. I myself find it to be pretty outrageous, but earlier I was reading, and all of the sudden it hurt really bad to exhale. It felt like stabbing on the left side of my chest, so I wound up laying on my bed for like, 30 minutes trying to find an easy way to breath without getting a stabbing feeling. Then towards the end of my trouble breathing, my back (the area behind the left side of my chest) began to ache badly. Then my jaw started to hurt. I was chewing gum at the time, so I umed it had something to do with that. This was like 1 hour ago, and it still hurts a bit to breath. And I also thought my breathing was asthma related, because I used to have a severe asthma problem when I was young, for an example of the severity of my problem, I was on a name to name basis with many of the doctors in my local ER. But later, when I looked up my symptoms (extreme pain in chest, back aching, and jaw pain) I kept coming up with heart attack
