Perhaps peer pressure within the Slytherin house. If there are other students who make comments about appearance or status, it could lead Draco to develop an eating disorder. Also, his family's reputation might play a role. He may feel that he needs to be perfect in every aspect, including his physical appearance, and thus start to control his eating as a way to achieve that perfection. Additionally, any feelings of inadequacy compared to other students like Harry Potter could also contribute to this disorder.
It could be due to his own insecurities that are magnified in the fanfiction world. He may be insecure about his place in the wizarding world, his relationships, or his future. These insecurities could manifest as an eating disorder. For example, if he feels that he's not as popular or well - liked as some of his peers, he might try to change his appearance through controlling his diet. And the constant comparison with the Gryffindor students, who seem to have a different kind of confidence, could also be a factor in driving him towards an eating disorder.
One cause could be the pressure of living up to the pure - blood family standards. He might think that a certain body type or appearance is expected of him. Another possibility is the stress from his role in the wizarding world's conflicts. For example, the tasks he was given during the dark times at Hogwarts could have been so overwhelming that it affected his eating habits.
One common theme could be the struggle with self - image. In many fanfictions, Draco might be depicted as feeling pressured to conform to certain ideals, whether it's the pure - blood standards in the wizarding world or just general expectations of appearance. Another theme could be using the eating disorder as a way to cope with the stress and guilt he may feel from his actions in the main 'Harry Potter' storyline, like his involvement with the Death Eaters.
A really interesting fanfic could be one where Draco's eating disorder is intertwined with the magic system in the Harry Potter universe. For instance, perhaps a spell gone wrong has affected his relationship with food, or there's a potion that is supposed to cure it but has unforeseen side - effects. These types of fanfictions can offer a unique and creative take on the concept.
I'm not sure about a specific 'draco eating disorder fanfiction' that is considered 'good'. However, when looking for fanfiction in general, platforms like Archive of Our Own might be a good start. You can search for Draco - related stories there and then filter through to find ones that deal with the topic in a respectful and well - written way.
Eating disorder fanfiction is a type of fan - created fictional writing that may incorporate themes related to eating disorders. However, it's a rather concerning and potentially harmful genre as it can romanticize or misportray these serious mental health issues.
One possible theme could be his struggle with self - image. Harry has always been in the spotlight as 'the boy who lived', and this added pressure might contribute to his eating disorder, so the fanfiction could explore how he copes with this newfound self - perception.
One possible plot could be Alexander's journey of struggling with his eating disorder, how he hides it from his friends and family at first. Then, as the story progresses, a close friend might start to suspect something and tries to help him face his problem.
There's a story called 'Breaking the Chains' which is also quite good. It delves deep into the psychological aspects of an eating disorder. The author does a wonderful job of portraying the internal battles the character faces, like the constant self - doubt and the fight against societal pressures related to body image.
One way is through his relationship with food. For example, he could be shown pushing food around on his plate at the Hogwarts feasts but not actually eating much. Maybe he's overly conscious about his appearance and thinks that eating less will make him look more 'pure - blood' elegant. Also, his friends or family might notice his strange eating habits gradually, like how his mother might see he's losing weight but he keeps making excuses about being too busy to eat.
One possible cause could be the aftermath of the war. He was on the losing side, and he might feel guilty for the things he did during the war, like helping the Death Eaters. He might be haunted by the memories of the violence and destruction he witnessed or was a part of.
One possible theme could be the struggle of the character with the eating disorder while also dealing with the complex relationship dynamics brought on by imprinting. For example, how the imprint bond might either help or hinder their recovery.
