Dear friends,
Natural speed please, with a bit of acting !
I'm fed up with him!
I'm sick and tired of her!
I can’t stand him anymore !
She gets on my nerves !
It makes me so angry !
She drives me crazy !
He is so annoying !
It is unfair!
It is not fair!
That's enough !
I think that French keyboards autocorrect and put spaces in front of punctuation. :)
Since you asked for a 'natural' reading, I made the usual contractions. It would be very strange not to contract: It's / That's.
It is ok not to contract "He is' because it's possible to give slight emphasis to each word because of the annoyance that is felt. 'He' is a relatively important word. In contrast, 'it' and 'that' have less psychological weight. They are grammatical place markers whereas 'he' refers to a real subject noun.
