Why would they get mad for not feeling well and waking them up? If any of our children were in pain and we were asleep their dad and I would definitely want them to wake us up. You could be having heartburn
so try sitting up and see it that helps but you should go wake them up, especially since you are having pain in your chest. You are probably okay but it's best to let your parents decide. Go wake them up and just ask for help in figuring out what is wrong and how to feel better and that you are worried.
