I keep dying on Minecraft when I respawn?

Just recently I was playing minecraft and I have 2 hearts left, but when i die i reload the world but because of autosave it spawned me above the block and i keep falling to my death how to fix?

Lol record it and send it too me i need a good laugh

Try reloading another save instead of hitting respawn. If that still doesn't work, pause immediately after you spawn, quit, and reload the game. If none of this works at all, then you're out of luck
