A short hiatus might be in order, @booklove, and there's nothing wrong with that. True, you'll have to notify your readers, and believe me, I think we all can understand the feeling of urgency that comes with a webcomic. Pages usually take so long, that the rush to push them out as fast as we can can really weigh on our mind.
But if it gets to the point that you don't want to draw... well, then you have no other choice. Take a break. If you continue to push yourself, that is, to force yourself to draw... well, the problem will only get worse. Now, having said all this...
it's possible that there is another reason for your sudden lack of motivation. In addition to taking a break, then, I would also recommend you try to investigate and look into the reasons why you may suddenly feel so unmotivated. In either case, spending some time alone with your thoughts should help you figure that out.
Good luck, Booklove. And come back stronger than ever.
