As a Samaritan volunteer for three years, I talked to a large number of people in various stages of suicidal thoughts, from the depressed, to the potential suicides, to in a couple of cases, people who did go on to kill themselves, despite the efforts of myself and others to reach them.
From that experience I developed a empathy for suicidal people, without direct understanding based on experience.
Thirty years ago I had a complete psychotic breakdown, I spent three months in a psychiatric hospital, and a year off work, and I remain on medication, probably for life.
From that experience I developed a direct understanding of what suicide means, I only survived by sheer mental strength and willpower.
From my combined experience, I can tell you this much -
Suicides, including methods and reasons, are as unique as the individuals who commit them, every single one is different.
From personal experience, I can tell you that suicide is not a matter of wanting to die, it's purely a matter of being unable to live, which is a very very important distinction.
I can also tell you that, as far as considering the impact on loved ones left behind, such thoughts have been left behind a very long time ago. The suicide is in a place of utter mental and emotional isolation, and thoughts of anyone else are not possible.
That may sound 'selfish' - but we are talking a mental state where on the self actually remains, everything else is lost and unreachable.
The suicdal person is simply unable to continue living feeling this way for another ten seconds, there is no concept of rescue, or help, or being able to reach out for suport, these things are all long gone.
When you reach that stage, death becomes a seriously attractive alternative to what you are living through, you can stop the pain, and stop suffering.
In some cases, you want to hit back one last time, which is why violent suicide is the option for some people.
But be assured, it is not a matter of being 'brave' or 'cowardly' and it is certainly not a matter of thinking about other people.
You just have to want the pain to stop badly enough, to make it stop.
You just have to be desperate enough for some peace.
