Some very thought provoking words on this thread and my thoughts are with anyone affected by this.
What has surprised me recently is how quickly a series of events can overtake you and the speed with which how you lose the perspective to see the wood from the trees and with it the ability to pick yourself up without external help. Luckily I was coerced into seeking help by my partner before things got too bad although I still take things a day at a time.
Whilst outside the demographic mentioned by the OP I can certainly see why people feel they have no choice but to take their own life and unfortunately don’t seek help (or don’t feel they are worthy of help) with the associated stigma.
Unfortunately one only has to look at the suicide rates in Greece, Italy and Spain to see what impact an economic downturn can have across all age groups.
