Tw. Mentions of Eating disorders

Hello, I'm f15(she/her). I'm not sure if this counts as looking for medical advice, but I don't think it does because I don't have a eating disorder. Sorry If it does.

I don't eat a lot. I just don't care enough to go and make something to eat, and im not that hungry anyways. When I do eat, most the time I just feel nauseous.I'd rather do something fun instead. But now my mom thinks im devolping a eating disorder? She asked me if i ate anything today. ( its around 5pm when she asked) and I told her I didn't she told me I'm gonna devolope an eating disorder. But I'm not devoloping an eating disorder? I like my body, and its not like im depriving myself of food. I just don't wanna eat because its boring and exhausting. Yesterday she kept telling me to get on the scale. But I don't wanna. Its weird. Yeah Ive lost weight. But its not that much. I don't know what to do.
