Mama (2010)

The main character is a man in his forties with unsolvable physical problems (weighs over 200 kg), which entail psychological ones. He barely fits in a public toilet stall and escapes from loneliness in an imaginary love for a mannequin in a nearby store. The only living person to whom he is sentenced is his mother. He shares a miserable home with her, she can tolerate his snoring, although she silently suffers, and tyrannizes him in her own way. Apparently, only death can separate them.
