My Blocks aren't breaking

Hi! While I was playing minecraft, I decided to play survival. I chose the newest version, and when I started playing none of my blocks broke! I either had to break it 4 times or wait about a minute in a half for it to break. When it would break, I usually wouldn't get the block! I tried switching to other versions, but they did the same. I deleted that world, thinking it was just that one, but it didn't work for any others either. I switched to creative and it worked perfectly then. What is going on?
