Kristin Davis says that she believed that she would drink herself to death before her 30th birthday.
The 'Sex and the City' star says that alcoholism runs in her family and she feared that her drinking, which started in her teens, would lead her to demise.
Kirstin, who is now 43, said, "I really didn't think I would pass thirty. I drank a lot when I was a teenager. I had a fatalistic viewpoint".
Her parents moved to South Carolina when she was just a child and she says, "I felt like a misfit. I was in the South, everybody was blonde. I just didn't feel like I fitted in. It was sort of my way of fitting".
She gave up alcohol at age 22 following a stint in rehab, after which she vowed to commit herself wholly to her acting career.
She told Marie Claire magazine, "I got into the acting program, it was very challenging, I was hung-over and I wasn't doing so well in my classes. I thought, 'Do you know what? It's going to be one or the other. I can't really have both.
Kirstin ended by saying, "I miss it. You don't go to rehab and then suddenly it goes away".
