When I was going through the diagnostic process, my therapist kept telling me "we don't want to change people's way of thinking for being autistic, that's no-win scenario". You could force yourself to eat everything someone throws at you, but what's the cost? You'll remember and feel that forever, and they'll expect you to be cured.
Be kind to yourself, the way you eat doesn't need to change if you aren't experiencing health problems. You are already eating normally even if that normal isn't part of your families normal
This is the first I'm hearing of that. Though I admit I don't use sm. I was given 100% for PTSD after going through an extremely stressful evaluation where the examiner deliberately triggered me several times. I say deliberate, but it was very subtle, if someone was faking it they wouldn't have noticed or even reacted.
On the flip side, I have a friend who is missing 10% of his brain to an IED, can't hear for shit, and can't walk very far because the part of his brain that is missing controls autonomous breathing - he has to think about it or he doesn't breathe. He was only given 30% and he honestly doesn't have the resources or mental fortitude to keep trying to get the VA to take care of him.
