Jennie Garth's divorce left her in ''excruciating pain.''

The former 'Beverly Hills 90210' star - who dropped 30 pounds following her split from 'Twilight Saga' star husband Peter Facinelli after 11 years of marriage last March - is still struggling to move on but knows the pain won't last forever.

She told Health magazine: ''When I'm in excruciating pain, like with what I've been through with my breakup and that grief and loss that's just immobilising, it helps to remember that it only lasts for 13 to 15 minutes, max. And then it's over. 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.''

The 40-year-old actress - who previously admitted it ''stings'' to see Peter with his new girlfriend Jaimie Alexander - revealed that she is interested in meeting someone new, just months after confessing she had jumped back into the dating scene again too quickly and was briefly linked to three men.

She said: ''I'm learning to date again. Looks aren't important to me anymore. I like positive energy.''

But the mum-of-three - who shares three daughters Luca, 15, Lola, 10, and Fiona, six, with Peter - claims she has never felt better about her figure.

She said: ''Every day, I just renew my healthy choices. I feel really good about myself now, and I don't want to do anything to change that

''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 admits. ''The worst was fasting with colonics for three or four days. It was the most horrifying experience ever!''
