Dude, go get some procrastination pills, they come in all forms like trap music and strangely heavy irish cream. Be sure to consult your doctor first though, as every individual reacts differently to each form and fashion.
Haha, I know that feel too. But it's not about being productive or lazy. Demand less from yourself as a whole (pressure to achieve) and you'll automatically get more motivated for things like this.
Consult a psychologist for fruther instructions. XD
