I think that at some point we have all pronounced the phrase that serves as the title of your publication friend @garybilbao, it is normal, the theme of constantly working generating content, "fresh ideas" sometimes exhausts, that is why the brain demands a certain periodic "reset" , so feeling how you feel is not only normal but a logical cause of the work you do, a little rest and distraction is not only good to "recharge batteries" but to generate new ideas for content and even share experiences.
Do not worry, I put the fatigue will leave that hardworking body xD
