I didn't read the responses to your post yet, so am probably doing a repeat here. Your situation reminds me of the days when I worked in an office. Although I was the business owner's secretary, I also typed for about a dozen account executives. (Some of them wanted really weird time-consuming/useless things typed up; those always went to the bottom of my pile.) Anyway, sometimes the pile got so high that I felt overwhelmed and could not function for a while. What I suggest to you is that you take a deep breath, separate your projects, and prioritize them, by whatever method suits you. Obviously that will not make them go away or make less projects, but you might find that it will help the panic go away. If the panic goes, you will feel 100% better and can get started on whichever project you've put on the top of the pile.
