I'm 15, female. A month and a half a go I broke up with my boyfriend of 17 months. Afterwards I stopped eating ALOT. I ate odd snacks when I had to and never finished a meal. Since me and my family noticed a big weight loss in me I've been trying to eat more but it hurts because my stomachs become unuse to bigger portions of food. Also I don't have any appitite I just eat when I have to but rarely finish. Before this I was already considered underweight for my height and I've became abit worried about myself. I don't want to eat and it just seems unimportant now but i want to eat for my family, help?
