I'm really scared about my health ?

You need to take a deep breath and calm down! Lie down on a bed or couch and concentrate on your breathing... think of nothing except for your slow breathing. After a little while place your palm onto the left side of your chest and you will hear your heart beat. If you don't, it doesn't mean you don't have one.... try feeling your pulse (upper neck, wrist or even thumb) Just remember that your heart is beating!
