Minecraft End portal city

I was going spelunking through the nether and had grabbed up three elytra and 23 shulker shells then decided to go back. I had all my diamond armor, my elytra that id already gotten which had unbreaking 3 and mending, 4 shulker boxes full of items, potions, enchanted diamond weapons and tools, etc.

I merrily sent my pearl into the portal and all of a sudden I was in the void dying with no time to react and I just really wanted to rant about it.

Btw I was playing on XBox not Java Minecraft, if that helps but I guess there’s no way to get my items back.
