Teen Mom Amber Portwood Talks Prison, Overdose Attempts & Mental Problems

"The depression took over. 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."

She continues saying, "I had been at such a low point, I couldn't go any lower," she said. "There's nothing lower than trying to kill yourself. That's why it's probably hard to understand why I did what I did.

"But when you mentally know that, you're not right. You're 22, and you tried to take your life twice. And you're 22, and you're still here, you don't want to mess that up."

"In my situation, I felt in the program there were a lot of eyes on me. And it was very uncomfortable. I was not using my anti-psych medication even," Amber said in the interview.

"You know, I was very depressed, all alone, all bitter at everybody.

I felt like that wasn't the life I wanted to live, I felt like I'd rather do my time, and get it over with, and make the best out of the situation that's been handed to me."

Amber's baby daddy, Gary Shirley, has held custody of their 3-year-old daughter Leah because of Amber's arrests, stint in rehab and subsequent jail sentence.

"I felt like I had no reason to even be around, because I was a mom. I felt like that's what I was put on this Earth to do, when I had her ... and I started partying and doing drugs because I felt like I couldn't do anything anymore. I lost my whole family, I felt like, they moved away from me," she said.

"I lived such a busy life and I woke up sometimes and was like, am I too busy for my family? And I felt so selfish. I was so depressed. It became kind of scary for me," she said. "I felt the same way I felt a couple years back when I, you know, tried to commit suicide. When I walked in a courtroom, I was like, if I don't do something, I'm going to have to."

Amber hopes that by entering prison long-term, she will finally be able to turn her life around for the better.

"You want to be free. Who doesn't? But you know if you can't do it, if you can't do it, why are you kidding yourself?" she said.

"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."

And while Amber takes responsibility for the direction her life has taken, she does attribute some of the hardships to being on a hit MTV show like Teen Mom.

"Getting money at a young age, going to parties where drugs were given to you, that's what really got me. ... You make your own choices," she said.

"It's like every time you go out to eat, you know, people are staring at you, talking, and it's hard. You get paranoid ... It's not normal, to always be paranoid."
