Smileysmile1966 - to address your comment about Paula Yates' suicide. I have a long history of depression, and was having suicidal thoughts as far back as when I was 14 years old, and the one thing that I have learned is that someone who is suicidal, is not thinking the same way as someone who is not suicidal - your perception of EVERYTHING is changed, and you can't see things that appear so clear to other people.
My cousin committed suicide, and at the time, someone described this to me as being an incredibly selfish thing to do - but that person was wrong. My cousin was in such mental anguish that she couldn't see the pain that her death would cause to her family (her widowed mother drank herself to death, and her brother was left with no immediate family at all) - all she could see was the pain, and the one way out.
I have never been in that dark place, but I have been close to it, so I can tell you that it is a horrible place to be. I have not committed suicide because the pain has not been bad enough for me to lose sight of my children and my husband, my family and my friends. But the pain was pretty bad at that point, and I can understand how, if the pain got worse, someone can see only the one way out, and cannot see the effects it will have on their family and friends. If Paula Yates was in that much mental pain, she may well have believed that the world, her friends and even her family would be better off without her.
It is easy and simplistic to say that suicide is selfish and someone who commits suicide is abandoning their family - but walk a mile in their shoes, try to live when every day is a uniform grey, weighed down by the sure knowledge that nothing will ever change or get better, you are worthless and the world would be better off without you - and then you may see how those skewed perceptions could blind someone to the effects that their suicide will have on those they leave behind - and you may be a bit more understanding.
