I lost all my items on my character and ender chest

I lost all my items but my world is ok but after I went threw the portal and went back home to sleep I closed the game and my Xbox I hop back on today with everything gone and when I join another old world it’s the same I want all my hard work back my netheirite amor tools wings, I put some old amor on but I can’t stand it all my hard work is gone and I’d like it back and even all my stuff in my ender chest is gone and I sent some old pictures to show want I had but I have none showing everything in my inventory
