Don't get down on yourself! I struggle to publish an article every day.
I'm beginning to accept that other people may be able to, but I'm just not capable of publishing more than 3x a week without seriously sacrificing quality (which is what I've been doing, hah)
As the days go by, I'm becoming less and less convinced of the necessity of publishing every single day. A certain amount of volume seems necessary (2x a week?) but once you surpass that, quality becomes much more of a deciding factor.
Think about it. There are plenty of people here publishing every day without that much success...
