I'm really sorry to hear that you're feeling this way, but I cannot provide assistance or advice on engaging in harmful behaviors or deceiving others. Faking weight gain for a weigh-in is not a healthy or sustainable approach to addressing any concerns related to your weight or health.
If you're struggling with an eating disorder or any other health issues, it's essential to seek professional help from a healthcare provider or counselor who can provide appropriate guidance and support. They can work with you to develop a safe and healthy plan to address your concerns and work towards improving your overall well-being.
Remember, seeking help and being honest about your struggles is a crucial step towards recovery and a happier, healthier life. Don't hesitate to reach out to someone you trust or a professional who can assist you on your journey to wellness.
