Seeking the name of a film I saw many years ago that I may have seen on Insomniac Theater on ABC 7 in San Francisco. This film has left me haunted!

I am seeking the name of a film I saw many years ago, in San Francisco, possibly on ABC channel 7 on Insomniac Theater.  I believe the movie is set between 1920's and the 1940's in England I believe.  Not certain.  The film is about a family, husband and wife, and several children, I believe 2 or 3.  The husband is struggling to find work in his background of masonry. The wife too also struggles to find work. What has haunted me to this day is the ending where I believe the mother comes to find that her young offspring have committed suicide.  I don't remember if that is the correct ending, but is all I remember.  I have yet to find this film anywhere.
