There's actually a very depressing (but really good) documentary about suicides at the GG Bridge entitled "The Bridge" http://www.imdb.com/title/tt0799954/
Love that movie if only because it is one of the few movies that actually deal with the subject of suicide - that I'm aware of. Watched it on Google Video during a particularly low point in my life last year. The fact that the filmmaker documented suicides as they were happening is a dark attraction of the film. For me, being in a dark place when I saw the movie, it helped me to visualize what I was contemplating. I guess that could work in either of two ways. In my case, it was a positive. Luckily.
