Losing everything on death

I was flying in my elytra and I did a nose dive to the ground because it was right next to my spawn and I thought why not? If I die, I die. So I did die. Then when I went to go get my stuff the only thing that was where I died was my armor. I lost everything that wasn't either in my secondary hand or in my armor slots and I cant find my stuff anywhere. I have spent hours in this world and and a LOT of my stuff was on me. Has anyone else been having this problem?
