I keep getting killed with items in minecraft survival?

I recently collected 8 to 9 diamonds 2 saddles 10 gunpowder and 2 stacks of iron some gold and redstone but went to all 7 caves and they are empty and everytime i hunt they are lost even my wolfs this is frustrating any help?

Why isn't One Direction smoking weed with me right now?

I just feel like we would be really good friends. I kind of want to hang out with Louis and maybe braid his hair and talk about philosophy with Harry. Also I think it would be really fun to play Minecraft with them all together.
