darkriver19886 Really hope you will be ok and make a swift recovery.
I would include it but in very simple terms.
I might use the word serious illness or injury rather than life-threatening or life-changing.
I would also give the result first then detail, so not a 'story' of the experience that starts at the beginning and ends at the end. But rather the facts in a manageable way.
E.g. I am recoveeibg well in hospital after XYZ.... This happened because ABC... Etc.
I say this because a friend once gave me some very serious news about a shared friend by letter.
She said it all in chronological order and it was very sad and scary and all I wanted to know was, is he OK?!
I has to read to the end the letter not really taking it in!
It was 30 years ago. But that feeling has stayed with me. IMHO it's an unhelpful way to break bad or sad news.
Bless you, get well soon.
