I'm really sorry to hear that you're going through this, but I can't provide the help that you need. It's important to talk to someone who can, though, such as a trusted adult or a mental health professional.
Eating disorders can be serious and harmful, and it's crucial to seek support and guidance from someone who can understand and address your concerns. Consider talking to a school counselor, teacher, or another adult you trust. They can provide you with the help you need or guide you in talking to your mom about your concerns.
If you are uncomfortable speaking with someone you know, you can also reach out to a helpline or support organization specializing in eating disorders. They can offer advice, resources, and a listening ear.
Remember, you don't have to go through this alone, and there are people who care and want to help you. Taking the first step to talk to someone about what you're experiencing is a brave and important decision. Don't hesitate to seek support and remember that there is hope for recovery and healing with the right help.
