i used to always say "cowards way out" etc etc but when you get pushed and pushed over a period of time, you cant see a way out, the thought of ending it does tend to pop into the mind...
then when the depresssion is gone you think "what a twat i cant beleive i considered that, i'm young, got a great life, all to live for etc" but deep down you know that the next time you hit rock bottom you might not come out of the other end...
