Game freezes every few seconds

My game continuously freezes for a second or two at a time. I cannot play the game, it happens both in multiplayer and single player. I tried restarting my computer twice and installed the latest java update. I forced a crash report and added the file below. I copied the game output from this same session to a text file and included it as well. My game was working fine yesterday :'( please help me. Thanks for your time.
