In MWI the universe constantly splits as different parts of it, including you, interact with each other, get entangled and decohere, leaving it in a superposition of nearly classical states, in this particular case a superposition of you’s that are dead, alive, barely alive, dying, living prosperously etc. There is no single “you” in this case, this concept does not even make sense. If you subscribe to MWI, you better give up the old notion of a single “subjective you”, they are incompatible.
