Yep, very familiar. at times it almost feels like my body is not very well connected to my brain.
With all information that does not or very late get processed. (like I only notice I am hungry like 2 or 3 hours after I should have eaten something, and than it just completely takes over everything and I cannot think straight)
Hunger is annoying, but with a schedule managable, same as habits of going to the bathroom, cold you dress according the weatherbulletin. But Heat and knowing where some of my bodyparts hang out is something that I struggle with regularly.
For cold you just put on another layer, for heat at a certain level there are no more clothes left to take of.
And with my body, at some days it's worse than others. with elbows that hitting doorframes, or other passerby's, small (scrape) wounds or bruises that appear on my body of which I have no clue about their orgins. It doesn't tend to be big things, so I can keep ignoring it and pretending it just is part of me. But on some days I wonder, but what if it did was something big, would I notice it?
