You will need to dig deeper today for the motivation to be productive, or get a friend to help you.
It could be hard to stay focussed on getting done all you have to do today, but you have this energy within you even if you have to dig a little deeper for it right now than usual. You need to be productive, so do not allow yourself to be lazy, find your motivation to get up and get busy. If you really cant do this, bring in a close friend who understands you for momentum.
