"What made me willing was hitting a bottom," the actress, 27, told Usmagazine.com at the Los Angeles premiere of Bra Boys Monday.
"It can be a spiritual bottom, it can be a financial bottom," she added. "It can be a combination of all of those."
She told Us she had gone to treatment before and "was on the right path, then I got off."
So she turned to her "wonderful family and people around me who helped me overcome all of this," she said. "People who loved me showed me what was at stake. Then I put myself fully into it. I stayed there for three months and did the work."
For those who don't have support, "find it," she urged. "Figure out where it is for you. You need someone to pull you back when you can’t do that for yourself.
"Also, believe that you have a positive future," she added. "People see through the mirage. They see your pain. People wanted me to be happy."
The actress — who will be appearing part-time on ABC's Dirty Sexy Money next season — told Us she now takes life "one day at a time. That's all you can do."
