Am i going to die PLEASE HELP MEEEE!!!!!!!!!!?

Calm down. It's the same for everyone. Even if your heart does stop, the ambulance guys will probably be able to resuscitate you. You need to chill out, there is a one in a billion chance that you're going to die, just because you can feel your heartbeat. I can feel mine right now. I can feel my pulse in about 3 different places, but I'm fine. Caaaaaaaaalm :)
