Explaining having an ed is exhausting

Ive recently found myself having to explain my ed more and more the past month or so and its driving me insaaaaaane. The second I say "i have an eating disorder" people rush to tell me that im so beautiful and weight isn't important then im stuck having to either accept their unneeded comfort or explain that i have ocd and that im not insecure about my weight or body but that im convinced everything I eat is 1. poisoned 2. Will give me botulism 3. Is rotten or 4. will make me sick somehow. I hate preforming my little rituals in front of people because how can I possibly explain needing to inspect my food and taking at least 30 minutes to eat ANYTHING. This has RUINED dates, hang outs, and family dinners. Im sososososo exhausted.
