The divorced happened soon after her best actress Oscar win for 'The Blind Side' and feeling "broken", Bullock withdrew from public eye.
The 49-year-old Oscar winner, who may be in the best actress race again with her role of an astronaut in 'Gravity', however, credits her three-year-old adopted son Louis for saving her, reported the Daily Mirror.
"I've been on the floor and I've been heartbroken. I didn't know how I was going to stand up. But I just gave it time. You don't think it will pass when you're in the middle of it, but it does. I'm so lucky to have what I have. I have a beautiful child and friends and family I adore," Bullock said.
"I was OK about being alone but when you have a child everything is about exploration and being around other kids and being out in the world and seeing things. So now I see things through his eyes. I haven't ever gone out and explored and done things before like I have in the last three years.
"I have the best life right now because I'm enjoying every single moment of this amazing human being. I'm learning how to have a good time through him," she added.
