After the death of her son, Gaines was diagnosed with postpartum psychosis, bipolar and schizoaffective disorder, the television station reported.
Now, Gaines is reaching out to help people with similar mental conditions.
"If there is another Naomi Gaines out there, you are not alone. Mental illness is not a character flaw. It is not a weakness to ask for help. It is a strength," Gaines told KARE. "What I wouldn't give to go back and say, 'I am not OK, and I need help.'"
Gaines now works part-time at the National Alliance on Mental Illness in Minnesota.
"I got the most help for my mental illness while incarcerated," Gaines told KARE. "That is when the prevention classes, groups, therapy and medication happened, after it was already too late for my son."
