Yes. People who know me, know that I find suicide (and not to be harsh about it) a cowards way out. When people commit suicide they are basically showing that they weren't brave enough to find another way out. There is always another way, and no matter how bad it may be, there is always a dawn coming. Whatever caused you to get this depressed cannot possibly be worth throwing away 20, 30, 40, 50 or more years of life that may be filled with happiness. How stupid is it to say that "Thing have been going so horrible for me." when you may have more than half your life left to be happy. No day, no week, can possibly be terrible enough to outweigh all your remaining years of life.
So yes, people would be extremely surprised. In short, it wouldn't happen. If I allegedly commit suicide, people know to investigate further.
