This is how I, and presumably most "well-adjusted" people will respond.  Of course no life has a meaning other than the one we create for it.  But, playing Devil's Advocate here, this line of logic means that the opposite viewpoint is just as valid.  If we are to create or derive the meaning of our own lives, then we should ultimately be able to decide that there is no meaning.  I've not studied much Nihilism or Absurdism, but understand the basic underlying ideas.  If we can't find a point to our lives, why continue to live them in search of this elusive, intangible, thing?  
I love being alive, even though I've dealt with my share of depression and feelings of complete worthlessness and aloneness.  I would never want to kill myself.  But, disconnecting from emotions for a bit, it's not really that illogical to decide to simply end yourself if you decide you don't need to exist anymore.  If an obviously intelligent, insightful man gets to be 35 years of age, it's safe to assume he's done a fair bit of searching and thinking.  Maybe he's decided that there's no point to his life.  Not an emo "my life is not worth living" kind of thing, but more of a decision of efficiency.  He's going to die eventually, he knows there's no ultimate goal in life, then why not just do it himself?  I'm an empath with an over active imagination, and I often wonder what my life will be like when I'm 70.  What if I never marry, or I marry and my wife dies.  Will I just sit and spend every day waiting for death to come?  Of course the answer most people will give is, no, go out and live your life.  But that brings us back to square one.  This probably only makes a small bit of sense.  I guess what I'm saying is that when I use my heart, I feel for this guy, and his family, and anyone who ever gets to the point of suicide.  I know there's plenty of life to live for.  But my logical side understands the nihilist rationale.
