Sorry to hear this.
You said he used to be in the military. The military is having big issues with this, something needs to be done. Just here at Fort Bragg I think they said in the last week or so, they had four suicides. It's horrible.
They make us all sit through the mandatory training, but people keep killing themselves. The training isn't really helping anyone, it's just the military trying to cover their own asses.
Until we start really helping each other, it will continue to happen, and it will hurt just as much every time.
