At time of writing I couldn't find a transcript of Rafa's post-final press conference but our member, piliii, watched it and posted this -
"I've just watched a little bit of Rafa's presser through the tournament's Periscope account. Only managed to catch the last two questions and Rafa looked very smiley and happy, not upset at all, he was even making jokes and laughing. He was asked about what he learns from defeats and he said it's always more entertaining to learn from victories than from defeats. He also talked about not being too harsh on himself after a defeat, that he's always self critical but he does not punish himself when he loses. When the presser finished he left the room with a big smile."
If Rafa's OK about it, then who am I to get depressed?
