Am i unhealthly or have an eating disorder?

so, i have always been told im thin, some say im too thin, but i dont feel very thin at all, i want to lose some weight, but people say im so thin it could lead to me being addicted and have an eating disorder, for some reason i like the feeling of an empty stomach, and when i have something sweet or fatty, i feel guilty. i dont know if i want to lose weight, or if i want attention, i know that sounds really wrong, so only supportive answers, and i have abmi of 16 and im 14 and 5ft6.5
