All wars disrupt; they leave behind the dead and the living
I'm not sure how much attention it has received, but I think a largely untouched field of investigation into the effects of WW2 and Stalinist oppression in Poland would surely relate to Polish death by suicide during these periods as a consequence of these events.
For example, my father had two friends who committed suicide in the 1950's because they (he believes) were simply crushed in mind, body and spirit, and couldn't cope, having survived WW2 and then having to live the nightmare of the Stalin years.
I'd be interested to hear if any other members have had family with similar experiences or have been directly touched by suicide committed during WW2 or the Stalinist era. In my opinion, the psychological aspect of 'winning' WW2 then being 'rewarded' with the imposition of an alien and oppresive regime cannot be downplayed or marginalised in this context.
