Heya mate here is your answer....
Antonio did not know why he was sad. He even disagreed with the reasons that were given by his friends - Salarino Salanio or Bassanio. The reasons given by them were :
1. He is in love.
2. He is concerned for his ships.
Ans Gratiano even said that he was a grave man.
But no one exactly explained why he was sad.
