The Wilson Phillips singer, who has said that she accepts her body's changing shape, insisted that she plans on getting back on a regular diet and exercise regimen in the coming months.
"I've had so much stress in the last year so it's really [been a] struggle. I never hide, when I walk down the street, someone's going to take my picture, that's what I look like. It's usually a s**tty picture. I'm definitely up in weight. I'm looking forward to getting an exercise routine again. It's like a daily decision. Am I going to eat healthy today or am I going to make some s**tty decisions?" Wilson told Fox News.
"I always think I am one of the the millions and millions of people that struggles with an addiction to food. I don't know how to relax, that's my problem. I can't smoke a joint, I can't have a glass of wine because I want 10 joints and 10 glasses of wine.
"That's my obsessive compulsive and addictive behaviour. I've really struggled since I've become sober. How do I balance that? How can I relax and not overeat?"
Wilson continued: "I have a lot of pressure in my life. I'm a working mother. I have a 2-year-old old and a 6-year-old. You try to pay the bills, you try to keep your life going and there's pressure. It's kind of a funny time right now. Negativity has thrown a dark cloud over this whole country and I feel for everybody.
"I feel very blessed in my life but I also work my ass off. At the end of the day I don't know how to unwind."
Wilson Phillips announced plans last September star in their own reality series about the band's comeback.
