Why?

Scotland has the highest suicide rate in the UK, according to figures from the Office for National Statistics.

From 1991 to 2004 the suicide rate among men was 50% higher in Scotland than other UK countries, while the rate for women was double that of elsewhere.

Having, after 5 years, just left a police department that dealt with sudden deaths, I can confirm the figures are appalling, but why? It's a question the bereaved ask anyway in each and every case, but why Scotland? Particularly intriguing is the fact that Shetland 'scores' higher than Scotland in general too.
