Johnnythefox nailed it already. And it is the same thing with death in general. Todays society somehow tries to cut out "death" in general, thats why all dead people in hospitals also just disappear pretty quickly. Down in the cellar - out of eyes, out of focus.
And there are just too many suicides to publish. In my country alone every 53 minutes somebody manages to catch the bus. You (as a state/nation/society) want the rest of the population to feel good and not give them the slightest hint that there is also sorrow, pain and hopelessness.
