The movie starts with the hero being fired because he saved the company in a law suit and now can never do anything like that again. When he gets home to be consoled by his wife he finds a note that she has left him. Every time he tries to talk to someone about his misfortune a new disaster happens. In the end he meets with his sister (?) who is dying of cancer. She tells him not to be so obsessed with himself and get over it, or something like that.
I can't remember any actors or the director. What is the name of this French movie?
I saw it between 89 and 94. I think it was from the same year.
