okay, so my stomach hurts. i get these hunger like aches on my upper abdomen, all day all night. i feel like throwing up, but i dont or cant. i never seem to get better. the pain is like now a way of my living, i get nervous like, (butterflies in my tummy) though there's no reason to it. i drink water, more than i used to, i've been like this for the past few months. the pains wake me up in the middle of the night. i get slight headaches,  i keep shaking between meals, which i guess is due to low blood sugar levels. never had sex, lol so im not pregnant. im 17 yrs old, female. i lost weight, im prbably 42kgs for 5'8. which i think is not good. anyway, i'd really like to know whats going on. thank u :)
