Not necessarily. You depend on sustained information consistency and resiliency.
But that doesn’t necessarily need to be mass based.
For example, you could exist encoded into gravitational waves or light.
And if the information of that universe is isolated, yes, you’d be dependent on its continuation.
But there’s a number of paradigms in cosmology where that’s not the case, from Penrose or Lee Smolin’s fecund universes to if there was any kind of cross communication between Turok’s CPT symmetric universes. Even more recent work on the black hole information paradox is pointing towards recoverable information being the case were your information to be swallowed into a black hole.
So if your existence is now data based, the question of longevity is very much tied to the longevity of information and not matter, which may be quite long indeed.

And certainly longer than a human body.
