it's absolutely what all people do. The missing piece is you need to (a) multiply the severity/effort required by an order of magnitude and (b) add in a whole host of co-occuring factors like anxiety, OCD etc. that often come along for the ride
yeah i don't disagree about breakfast specifically if it's completely standalone. However it's worth recognising that autistic people in burnout lose a LOT of executive function. Something seemingly simple like making breakfast can actually be challenging if they enter that state. It's really hard for someone who hasn't experienced it to even conceive.
Well if that's all implied by "proper" breakfast then it's pretty unreasonable to have to choose between "proper" and "skip".
It's multiplied in some situations. I'm skeptical of breakfast while alone being one.
