The Brazilian told the BBC, in an interview at his team's winter 'Wrooom' media event in the Italian Dolomites, that he had considered stopping.
"Yeah. I thought about so many things. I thought maybe I was finished. I thought about not staying in Ferrari. I did not know what would happen. So many things were inside my brain," he said.
"I talked to everyone," added the 2008 championship runner-up who came back from a near-fatal head injury suffered in 2009. "But I also did work with a professional psychologist, sporting psychologist.
"That was just the beginning. After that I was able to change the direction to think, the direction to work and I think it was like training I did. But also I think my family helps, definitely 100 percent."
Massa had an abject first half of last season, scoring just 23 points by the half-way point compared to team mate Fernando Alonso's 154.
The Brazilian had a far better second half, ending with a final tally of 122 points and securing a one-year extension after Ferrari had considered replacing him.
Massa said Alonso, a double champion, was the toughest team mate he had ever had including Germany's seven times world champion Michael Schumacher.
"I think I had more difficult times with Fernando, so I would say Fernando was the strongest team mate for me," he explained.
"But you learn with everybody. I learnt a lot with Michael, with Kimi (Raikkonen in 2007-9) and Fernando." (Reporting by Alan Baldwin, editing by Alison Wildey)
