Everyone is different in a crisis, Julien. I don’t know exactly how you behaved, of course, but your actions seem right on target.
Water, Band-Aids, weed, caring concern. That’s what I’d want! (Well, maybe minus the weed. I find it makes me feel worse if I’m in pain from an injury.)
Perhaps your partner wanted a little more soothing and warmth? I don’t know. I’m neurotypical (I assume) but I find it hard to cope when I’m around a person experiencing a lot of pain.
I think I often react just like you. I shut my own emotions down because they’re too strong for me, and I try to be as efficiently helpful as possible.
Not everyone behaves that way, but I know more than a few people who do.
I think you’re doing fine. I fell off my bicycle last spring and hurt myself badly. (Fred Shirley remembers!) I wish I’d had you around then. Sounds like you’ve got it together.
