For a week now i have been waking up with bad nausea and for about a year now i have had these random pains in my chest they only last for a few seconds though.......the nausea is so bad i can't eat and the pains in my chest are so bad i can't breathe while they're there. I cant be pregnant as I've never had any sexual contact!! please help me these sick feelings stop me from learning while im at school and i can't have fun going out with my friends anymore!!
