Just so you know, it's considered good form for journalists reporting on suicide to refrain from describing the method (to the extent possible)[0][1][2].

On a professional level, it is believed (and supported by some research) that this can be a trigger for people who read the article, potentially causing more suicides.

On a personal level (for you), you may want your brother remembered for his life, rather than evoking in readers' minds the image of his last moments alive.

While it's a tragic loss, it's purpose is moot because many people read the entire thing and still don't know what his symptoms were. If you want to desensitize the discussion about mental illness, you need to expose the underlying conditions and make people aware.
