It sounds like part of your problem is making a decision. Which reminds me of something I read. That people who have lost their emotions due to brain injury can't make decisions. They logic everything out and can't get to the point of, okay, this is what I'm gonna do, or the answer, or whatever. We on the spectrum do have emotions, of course, but we do also have a tendency to use logical thinking. I wonder if that is getting in the way of just making a decision on what to eat and doing it.
I don't mean that to be a complete answer. And it doesn't cover what to do about it, I realize. But I figure it's worth throwing out there for your consideration.
