"I was very depressed, I was alone, I was bitter at everybody and I didn't feel like that was the life I wanted to life," she told ABC News of downing a potentially lethal dose of Suboxone (which is used to treat opium dependency). "The depression took over. I took 30 Suboxone within three days. I'd just take four to five at a time underneath my tongue, and nod out. I had more than addiction problems. I had, you know, mental problems, too."

This isn't the first time Amber reportedly tried to kill herself. She was rushed to the hospital last year when ex-fiance Gary Shirley called 911 after finding her unconscious. In February she pled guilty to felony possession of a controlled substance and admitted to violating her probation. That sentence was suspended when she entered a court-mandated drug rehab program. Which brings us back around to today.

Amber says she opted to forgoe treatment in favor of jail time because, "In my situation, I felt in the program there were a lot of eyes on me," she says. "And it was very uncomfortable. I felt like I'd rather do my time and get it over with. Make the best of the situation that's been handed to me."

To that end, Amber plans to use this incarceration to her advantage, telling ABC News, "I'm going to take some classes, I'm going to get my GED, take as many programs as I can. You know, just try to better myself for when I do get out and not stay in prison ... I'll be off the drugs, I'll have an education to get me a job, you have to think of the positives in this negative story."
