I can't do spoilers. Warning of unpleasant real-world things below which are not for the squeamish.
Pretty much that, yeah. I was a child and teenager through WW2 and its aftermath, and that was how it worked. People shut up about it, and tried to get on with life. Sometimes that worked, often it didn't. Many of my family didn't make it, and some of those that did were left permanently damaged. My dad, in particular, had been captured during the Pacific War, by the Japanese, and had been a longterm POW, presumed dead, and had been tortured and otherwise very cruelly treated, including being starved to the point of nearly dying of beriberi and having his hands severely and permanently damaged. He had been an army medic. When we got him back there were years of nursing him through physical and mental damage, constant pain, screaming nightmares, the lot. When he finally remarried (that was when my brother and I were teenagers; our mum had died of TB when I was quite small, which is why we were raised by the grands and greatgrands) things got a bit easier, but it was never good.
My grandpa, also an army medic, was at Gallipoli. Enough said, I think. My favourite uncle was permanently damaged by mustard gas, in France. There's more, but enough horrors. The point is, all of these people went on to live useful and productive lives, after. Not the lives they could have had, but lives. And there was little help to be had, mostly none. A TPI pension and cheap or free medical treatment for the worst-off of them was about it. The world was overflowing with damaged people back then, and the resources to help them all didn't exist, even for those governments and societies that cared about their folk. Many didn't. I heard a lot about this stuff because even as a child I was someone to whom people told things (still am). And I lived through the aftermath, and am still here, living what seems to me, despite its problems, to be a fairly good life, because I am a stubborn b****.
Anyway, the point to this rant is just this: Minna has created a fictional world in which the background, the characters and the events depicted all seem to predispose to the worldview that s*** happens, you survive and then you go on. Damaged or not, grieving or not, broken or not. While this is, obviously, a far worse world than that in which I passed my childhood and adolescence living first on a hardscrabble subsistence farm, then in a very rough and ill-provided returned-soldier settlement, then in the Australian Outback, the aspect or 'survive however you can, happy or not, well-adjusted or not', definitely resonates with me. Many people had it far, far worse than I did. I have friends who survived the Nazi internment camps as children, were kids in London during the Blitz, starved in occupied Belgium.....(that latter person became a quite well known lecturer, writer and gardener, spreading the knowledge of how to grow and make the best of food in the most difficult of circumstances. Many of the others grew up to be doctors, conservationists, activists for the poor, the displaced, the forgotten. Their experiences shaped their future lives).
But none of these people had the benefit of the counsellors, therapists, psychiatrists that are nowadays taken for granted. And somehow they managed. The people in Minna's creation may very well manage too, and even turn out in some cases to be, or to become, decent folk despite their experiences and their deficiencies. I have been watching with increasing dismay the comments beating on the writer and the characters for being as they are, and wondering whether these commenters have forgotten their own empathy, sympathy and humanity, or have ever even met anyone less privileged than themselves?
Apologies for the wall of text, but it needed saying. End of rant.
**Edit**: In no way do I intend any disrespect to those who do need and use such services, nor any diminishment of their suffering. But I am saying: Minna's world is unlikely to have much of those facilities, and within the lifetime of some of us here present, neither did our world.
