I think I was having Chest pains.Help?

I started to have chest pains last night and I was afraid to go to sleep.I put my arm above my head so my heart could stop beating so fast(seems like fast i never check how fast my heart is beating)I finally fell asleep and so happy woke up this morning to a new day :).Thankyou Jesus.Heres some things about me:Im 13.a little over 5 feet,I ate meatload,mash potatoes,corn,apple pie,bread from a cheeseburger,gum,pepsi.chocolate chip cookies(on a few) and cereal(chocolate coco pebbles and the rainbow kind)3 servings.Thats what i ate yesterday.Could it be the foods?It started to hurt when i had my computer on the bed and me outside the bed with the side of the bed pressed into my chest where my heart is.It hurt for 1-2 minutes.Could that be why it hurts?I only had two symptoms of heart attack numbness and chest pain.I started to sit up this morning and it hurt.so what can i do?I dont even know what i can eat.what can i eat.GOD BLESS!PRAY FOR ME.ALSO I KEEP BURPING
