I am 17. Female. I normally weigh about 127. It seems like all a sudden I can't eat and keep wanting to throw up and I'm losing a pound a day.ive lost like 5 pounds now in 5 days I just never feel hungry and that's odd for me because I love to eat. Lol.but I don't know what to do and I told my mom but she doesn't seem to be worried about it. Shoud she be?
