Alentejo, the part of the country where I work, has the greatest suicide rate in the country (~28 suicides/100k in the coast region, 19 suicides/100k in the interior region, when the national average is around 10 suicides/100k).
Some say isolation, ageing alone, the economic crisis and poverty and unemployment are to blame. I suspect alcohol consumption has a lot to do with it.
Just a few days ago someone I knew ended his own life. I was away visiting family, and sadly I could not attend the funeral. He knew my great grandfather. I believe he was sick and didn't want to suffer anymore.
