In a recent interview with NewsWeek, Michelle gave a rare glimpse into her feelings since Heath's shock death in January from an accidental overdose of prescription drugs.
"I guess it's always changing," she said of her grief.
"I just wake up each day in a slightly different place - grief is like a morning river, so that's what I mean by 'it's always changing'.
"It's a strange thing to say because I am an optimistic person, but I would say in some ways it just gets worse. It's just that the more time that passes, the more you miss someone. In some ways it gets worse. That's what I would say."
She also has some fiery words for the paparazzi that hound her and her daughter with Heath, Matilda Rose.
"It burns a fire inside of me, the s*** that I've seen people do to get at me or my daughter," she said.
"I won't forget it, and I wont' support it. I don't want my daughter growing up feeling spied on or threatened."
She especially can't stand female paps, confessing that she told one off once.
"I said, 'You're better than this. Look at you! You're young, you're able-bodied, you have a brightness in your eyes. You're above this.' But you know what? She didn't go away," Michelle fumed.
The glare of the media is so bright, Michelle is considering leaving showbiz for good, in order to have a quiet life with her daughter.
"If it gets to the point where I can't situate my life in a way that they stay away more, then I'll drop a match on the thing," she said.
"I'll be sad. I like to act. It's saved my life over and over again. It's given me a sense of self-esteem, self-worth. I have this thing that I'm in love with - acting -- and now it has this baggage."
