My final point and this is more personal.
Is that I have a congenital defect which impairs me physically. Thankfully I can do daily stuff ok. However my whole life I've never been able to take part in any sports, gym classes, ride a bike, or move fast if I need to.
I have spent long stints in hospital during secondary school with plenty of pain and recovery etc.
The (now less popular) born in the wrong body idea. And the 'comfortable in your own skin' comment just now I think can land quite heavily to people with disabilities.
I was never comfy with it. How could I be? It set me apart, I couldn't join in, even stuff like catching a bus people I would be with would run off and I'd be left behind.
Then the OPs of course.
Coming to terms with this for me was a very very long process and it did affect me very badly from about 9 to 30 maybe. I took massive risks. I felt I was on limited time.
In my head I can run and jump. And dance normally. I wonder what it's like. I would love to know that.
Loads of people in that sort of position.
