Anonymous
i just balled my eyes out crying and now i can't take a deep beath or straighten my back
i feeel this sting or really sharp pain on the left side of my chest

it can't be a heart attack im only 21 years old and dont really smoke and stuff
and no other symptoms (i think) and i feel fine

what could it be? how od i make it go away?
