Question?

Have you ever thought of not writing anymore? Have any of you ever had a moment in time where you wondered, 'Is this something that I should even be attempting?' This has been my life these past few weeks. I'm not sure where this seed of doubt entered my mind or even how it did, but this has been my struggle presently. I even tried to stop writing, just to see if I could... well let's just say it was the worst week of my life. I found that even though I wasn't putting pen to paper, my mind would wander and I would be mentally noting the story even if subconsciously. 

This is my question for theprose.com world. Have you ever thought of not writing anymore?
