6000 Veterans Commited Suicide Last Year! , page 1

Does it bother anyone here that 6000 veterans have committed suicide last year? (2009) this was just brought to my attention today, and it is not sitting right. What is causing these soldiers to kill themselves, and why has it been kept quiet?
I have a few friends who are veterans of the current war. their mental stability is obviously shot, and i of course feel for them understanding with what war can do to someones mind. www.defense.gov... www.armytimes.com...
