Abidal returned to training with his Barca team-mates last week, eight months after undergoing his transplant operation.
"I feel good. I'm eager to fight and to return. At times it was tough when I woke up in the morning, but little by little I've trained with the aim of returning and this helped me," he told TV3.
"I never thought about stopping playing because football, apart from my family, is my whole life."
He added: "I really wanted to start kicking the ball again. I knew that once I'd touched it again, the path to recovery was a little shorter.
"You always need to try it. If you don't do it, you don't know if you can. That's why I wanted to train, to know if I was capable."
