how am i supposed to get my stuff bruh

this is a mediumcore world, my stuffs towards the left by my house where i died and so are all my chests, so i cannot reach any weapons to kill them, and if i try to kill them with my copper shortsword itll literally be impossible since they will respawn, i tried everything i went left i went right i tried to knock them back with all three of my tools i cannot reach my stuff in time and j cant leave or my stuff will despawn, the only reason i gotta deal with all of this is because i thoight it would be fun to have them follow me as pets and i was low and i was running over to my nurse amd i died before i could run in my house
