Scott was found dead in her apartment in New York on March 17. Her assistant found her hanging by the door handle with a scarf wound around her neck.
The 70-year-old lead vocalist of The Rolling Stones said he is thankful to people around him for supporting him, reported Ace Showbiz.
"I'm doing OK. It was difficult, you know, very hard year, but I got back into it by working on touring with the Stones in Europe, and doing other things, including this great movie. (I've gotten) a lot of support and I really appreciate that," he said.
Jagger, who was on tour at the time of her death, cancelled his concerts and went back home to attend her funeral in California.
