If your religion instructs you to fast and you’re recovering from an eating disorder:
It’s okay. I swear, it’s okay. I can’t fast and I know he understands. Your god, goddess, or whomever will understand, I promise. If you do feel that you need to fast, be safe. But I promise that they will understand if you can’t fast. They want what’s best for you. Look up alternatives to fasting if you need to, I promise they will appreciate whatever you can give and they want you to be safe and healthy.
