Depression, unfortunately, is no stranger in our society these days. It can take many forms, from a brief period of passing sadness to an unshakable chronic state of the blues. In the worst of cases suicide becomes a real threat, and recognizing the symptoms can mean the difference between saving somebody's life or letting them die from a treatable illness.

The symptoms of suicide, courtesy of WebMD:

• Talking about suicide/killing oneself
• Frequently talking or thinking about death in general
• Making self-depreciating and negative comments about being worthless, helpless, or hopeless
• Making statements like "it would be better if i wasn't here " or "I want out"
• Losing interest in things they used to care about

• Having a "death wish" by taking physical risks and tempting fate
• Saying goodbye to people
• Going from very sad and depressed to suddenly happier and at peace
• Putting affairs in order by tying up loose ends, changing will, etc

If you notice any symptoms like these take them seriously and seek professional help immediately. In a situation where suicide is a possibility it's much better to overreact than under-react.
