Black rectangle, really??! But jokes aside, it is good to let yourself feel how you feel about things. In this case, writing and creating stuff. Of course, the first rection is probably along the lines of nooooooooo, stay, keep going! But I know myself similar feelings about similar things I think. Maybe it is a burnout. Maybe there is not much more to give. Just take your time and follow your heart. And I sure hope to see you pop up around on the chain. Cheers!
