What you described, at least in my personal expirience, looks like mild overtraining, or overreaching, as it's also called. Like the name says, you reached a level where you body can no longer keep up with the imposed demands.
It is usually cummulative, product of series of workouts. Most likely, as Minotaur suggested, that kind of work was too much to begin with.
But, it's nothing that a week off won't fix. You might want to follow it with a program which is higher in intesnity but lower in volume. That would constitute an accumulation/intensification cycle, and you would most likely end up bigger/stronger at the end of it all. There is CT's article "7 Tips" where in one of them he goes into detail about this. Also read stuff by Jack Reape about taking time off and how beneficial it can be.
Most importantly, analyze your training log. You now know where your "breaking point" is - how much volume and how much time it takes. See that the next program you decide to do has comparatively lower volume than that.
