"I feel extremely proud of myself," she said. "I'm so happy I'm overflowing with joy. I'm sitting here tearing up cause it's hitting me that today at the age of 49, ex-drug addict, ex-prostitute, ex-gang banger, I'm getting my diploma. I'm truly blessed. God is good!"
Catarina came from a life of abuse, dysfunction, and pain. She took to drugs at a young age and spent five years in the Valley State Prison for women.
"Along the way, I had children - seven to be exact, which I lost custody to all but one. But I've been clean seven years, been out of prison 10 years and I got all my children back in my life today. I'm so grateful for life today and I'm truly blessed. It feels so right to be in my own skin. As I look back it's only to remember that I've come a long way and I never wanna go back."
