Are you [Ever] Afraid to Write?

There are without questions times where I am afraid to write. Some days when I have had a emotional day or a day where I don't feel I may be thinking clearly, I am afraid to write. I am scared that I may write something that I don't believe or that if I read my work in a day or two, I may not agree with what I had written down. For me to be able to write clearly and focussed, I need to be in a calm state and my mind should be overflowing with thoughts solely about writing. I find it hard to write on days where my thoughts are subconsciously thinking about something else and concentrating on things other than writing. It is on days like this where I fear my own writing. With all sorts of different thoughts and ideas prancing around my brain I can't be sure what will actually turn up on the piece of paper. I take my writing personally and feel like I should be able to support and be confident with everything that I write, Jacques Derrida and I are on the same page when we can state that we take the act of writing seriously.
