English Language Help Please

I'd probably have gone along the tautology line, but its not really tautology, is it.
It seems similar to a tag question too, but it's not a question either!

Had a look on Google, could it be epanalepsis?

It's defined as a rhetorical term fot the repetition of a word or phrase at regular intervals
or
repetition at the end of a clause or sentence of the word or phrase with which it began (a combination or anaphora and epistrope)
No idea if that was remotely helpful!

Honestly, I think you may have just saved my life
