I mean, if I die instantaneously and painlessly, and conciousness is seemingly continuous for the surviving copy, why would I care?

My conciousness might not continue but I lose consciousness every day. Someone exists who is me and lives their (my) life. I totally understand peoples aversion to death but I also don’t see any difference to falling asleep and waking up. You lose consciousness, then a person who’s lived your life and is you regains consciousness. Idk
