I'm really sorry to hear that you're struggling with an eating disorder. It's important to talk to a healthcare professional about your situation, as they can provide you with the best advice and support tailored to your needs. Eating disorders can be complex, and weight changes can vary widely depending on many factors, including your specific behaviors, metabolism, and overall health.
If you're not gaining weight, it might be due to restrictive eating patterns, excessive exercise, or other behaviors often associated with eating disorders. However, the focus should be on health and well-being rather than just weight.
Please consider reaching out to a doctor, therapist, or a support group specializing in eating disorders. You're not alone, and there are people who can help you through this.
