Can't open inventory or chests.

Howdy, I've recently found a bug which unfortunately is making the game impossible to play. I no longer can open my inventory or craft anything. If you click left trigger it just swings. Like opening a door. 

 

It happened shortly after I created ender eyes I got onto a minecart and rode it to another house. I used one button connected to Redstone and a repeater. Then when I tried to saddle a horse. I noticed because it would let me get on the horse but not control it. I then realized I could no longer use my inventory. I tried to quit and get back in. It did not help. I had a creeper kill me and it still does not work.
