i'm sorry if my grammar and spelling is incorrect, because i am still suffering the pain right now. it was about a few minutes ago, i've only slept 4 hours today and then i feel very sleepy. at the same time me and my bro tried to play-fight by kicking. i have a very bad sleeping habit, and i am very weak in sports and all the athletic stuff. i cannot run much because my heart beats fast and hurts, it's been happening all the time. so now it happened, i was trying to make a taekwondo bullet for show, and then this sudden extreme pain happened in my heart or chest.. my heart began to pump a lot faster and deeeeper. i tried to cough as well but it would heart, i'm trying to breath deep.. i took a 7 seas garlic oil vitamin and still nothing has happened. it still hearts when i move and just by breathing. it's still not calm even though i've been dozing out for minutes. i don't want this to happen, is this a serious problem?! IT HURTS A LOT I JUST DON'T SCREAM.. i'm 14 years old, help..
