Fear and (No) Motivation in St. Louis

I have not accomplished any writing for at least a week now, possibly somewhat longer. I've lost track, actually. So many things are going wrong for me in my life that I have trouble picking up the pen and putting it to paper. I've finally tracked the phenomenon down to fear, in the last couple of days--fear that I will fail in my writing, too. Fear that my work will get rejected again, as it has countless times before. Fear that I really can't write after all, because I don't have any talent, and that people are only lying to be "nice" when they tell me they like my work.

I guess I figure that since nothing else is going right, why should my writing? I'm thinking in particular of the short story I sent in to a magazine, which I am waiting to hear back about, and also of the novel that I am currently close to finishing.

So how do you get over the fears and start to write again? How do you make yourself pick up that pen? Do you just write through the fear, or do you need to do something, a cleansing ritual or what have you, before you can again? Thoughts and advice, my fellow writers?
