Writing, for me, is definitely an extension of myself...one I am lost without. I went through an extended period of time were I was emotionally conflicted and deeply depressed, and unable to write creatively or otherwise. It was like being lost in an endless desert, with no water! I thought I had lost the talent, and it made my heart ache with an emptiness that was almost unbearable. So I know what you are talking about. Fortunately, I found my way out of the desert and its like having my eyesight restored after a period of being blind!
