Meaning
Thoroughly, intensely tired of something unpleasant, to the point of exasperation.
It’s a hyperbolic intensifier — nobody is literally dying of exhaustion — used to signal that ordinary patience has been completely used up.
Origin
The phrase is a straightforward hyperbole, pushing “sick of” to its most extreme possible conclusion by adding “to death,” the ultimate endpoint, purely for emphasis rather than literal meaning. This kind of exaggerated intensifier is common across many English expressions of frustration (“bored to death,” “scared to death”), where death functions as a rhetorical ceiling rather than a real outcome, and the specific combination with “sick” has been in everyday use for a long time as one of the more forceful ways to express that a limit has been reached.
Examples

A: Still dealing with the same printer issue? B: Yes, I’m sick to death of it.
