Jennie Talks 'Excruciating Pain' After Divorce

It's been nine months since Jennie Garth separated from Twilight star Peter Facinelli after 11 years of marriage, and in a new interview with Health magazine, Jennie reveals that she went through "excruciating pain" from the split, calling certain moments "immobilizing."

"When I'm in excruciating pain, like with what I've been through with my breakup and that grief and loss that's just immobilizing, it helps to remember that it only lasts for 13 to 15 minutes, max. And then it's over," she says about dealing with the split. "Your mind is ready to go to something else. You might come back to it, but it helps to just know that that pain is not going to last forever."

And Jennie has since moved on, admitting that she's stepped back into the dating game.

"I'm learning to date again," the Beverly Hills, 90210 star says. "Looks aren't important to me anymore. I like positive energy."

Garth also reveals to the magazine how she shed a whopping 30 pounds from her five-foot-five frame in 2012, after years of fad dieting that backfired.

"My biggest regret is putting my body through fad diets: Atkins, cleanses, the hCG diet. I lost like 18 pounds, but it came right back," she shares. "The worst was fasting with colonics for three or four days. It was the most horrifying experience ever!"

"I put Post-it notes with quotes or reminders of my awesomeness on my mirror. My favorite is: 'You are enough.' So often we walk around and feel inferior -- not smart enough or thin enough. It means that I'm enough exactly the way I am."
