HELP! I lost all my stuff!

So I spawned into the game,and logged in and immediately I fell from a great height. I died and all my items disappeared. I don't even know what happened, because when I logged out last time I was in the entrance to the arena on the ground, and not in mid-air.

So what I'm asking is if Melissa, T0MBIE or any Moderator or Admin can give me my items back.

The items I lost:
Diamond Sword with Sharpness V, Bane of Arthropods IV and Fire Aspect II
Diamond Sword with Sharpness I
Diamond Sword with Sharpness III and Knockback II
Diamond Helmet with Fire Protection I
Diamond Chestplate with Blast Protection I
Diamond Leggings with Protection I
Diamond Boots with Protection I
2 Health Potions
7 Gold Ingots
4 Gold Nuggets
4 Glistening Melons
32 Netherwarts
Enchantment Table
Iron Helmet
Iron Chestplate
