Minecraft from the end to the normal world?

I went to the end today to defeat the ender dragon.

i went to the other world where you can defeat the shulkers. I'm now wondering how I can get back into the normal world.

I didn't remember the coordinates from the spawn in the end.

is there a way to come back without dying?

As far as I know it doesn't work

You can only enter the overworld from the end through the portal or by dying. You can get to the islands, which you probably mean, and back via the small portals, whereby you need an ender pearl or by simply building yourself there (that would be ~ 1000 blocks away). Otherwise you can secure your items by building an enderchest, for which you have to have wood with you if I'm not mistaken (for the workbench).

You have to use an end gateway. These are these things:

They appear in random places on the outer islands. Just search for it, you will find one. When they are charged, they emit a beacon beam that you should see from a distance.

When you find one, throw an Ender pearl in it. Then you will be teleported to the end spawn.

PS: The coordinates of the end spawn are x: 100, y: 50, z: 0. But since the outer islands are thousands of blocks from the main island, it would be a better idea to just look for such a gateway.
