She seems to be prepared to come back and "do whatever it takes" for the sake of the health of her next child. In care is better than dead from malnutrition and treatable disease.
As bonkers as it might seem I can understand the "no regrets" line. She's currently in a refugee camp, 4 years after running away from a relatively comfortable home to go to a warzone, experiencing death and violence up close. I can well imagine too many regrets right now = instant disintegration. Without even rationalising it, it's likely a survival mechanism.
