Seems that way. Know two people in the last 6 months that have shot themselves in the head. A former co-worker and one of my good friend's dads.
Subliminal messages in our cell phones are saying "shoot yourself in the head", so really it's no surprise.
Simple suicide rarely results from insanity. Crazy people take everyone else with them. Ordinary people experiencing desperation, loneliness and a feeling of helplessness is usually the trigger for someone ending their own life.
