I noticed a doctor on the Cancer Community suggested you speak with an older family member; I think it is VERY important you do so and/or see a Dr. to address your concerns.

Have you discussed these terrible symptoms with your parents?
It sound as through you can't handle this pain you are in . I do not think this community can give you an answer. You need a doctor to look you over. Call the hospitol and speak to a professional.
