How did you know all of your writings had been voted down? I don't know there is a way of knowing? It is not in the feedback.
But to answer your question, I will just keep on writing. I know you must be feeling down right now, so take a break. Watch a little TV, or play a word game.. that will take your mind off about your the negative feedback.
Today, I got a nasty comment in one of my hubs.. it was a typo but the person was mean and insulting. Good thing we have to approve all comments first, so I just deleted it. But it bothered me.. so I went to the store and bought some ice-cream. Come to think of it, I should have had a chocolate bar. Chocolate and ice-cream have the same effect to me. I feel much better now.
What about you? What is your comfort food?
