While the girls seem to have persevered, mental health experts suggest that they may have an illness that needs urgent attention.
"It's an illness that is making them have nightmares," Taiwo Lateef Sheikh, a neuro-psychiatrist and former medical director/CEO of Federal Neuropsychiatric Hospital, Kaduna, tells
The ICIR after learning of the girls' condition.
"The children have suffered an illness as a result of the catastrophic and severe experiences they had, and also as a result of deprivation they're presently going through. It's because of that they're having nightmares, seeing their dead parents in dreams," says Sheik, who is also a professor at the Department of Psychiatry, Ahmadu Bello University, Zaria.
The girls' struggle resembles today's experience for millions of children whose life trajectories have been altered by the insurgency. But despite the number of children and caregivers in need of psychosocial support and life skills activities in 2018, only about one-thirds were reached, according to the last November's
humanitarian situation update from UN Office for the Coordination of Humanitarian Affairs (OCHA).
Following renewed attacks by Boko Haram,
displacement has increased, leaving more than 2 million girls, boys and caregivers in need of psychosocial support, according to Unicef, the UN children's agency.
As violence defines the affected children's world, aid workers say the war has inflicted enormous psychological damage.
"We have asked children in their classroom to draw what they are thinking, and seen a child drawing a pistol because that is what they used in killing his parents," says Elizabeth Maiyaki, child protection and case management supervisor with Plan International, who has been providing psychosocial services for unaccompanied and separated children.
The traumatised children show other signs of suffering. "They don't eat well. They don't talk. They're shy. They're lonely. Very aggressive. Easily angered. They don't associate or come in the midst of people. Sometimes, they could be stubborn. They easily fight among themselves," Maiyaki says.
Boko Haram's decade of insurrection to enthrone an Islamic caliphate in north-eastern Nigeria has resulted in accumulated tragedies: tens of thousands of people killed, about 2 million displaced, more than 7 million in dire need of life-saving aid, about 120 children used for suicide bomb attacks, mass abduction and rape of girls, and nearly 400,000 children with severe acute malnutrition.
But the cost of the insurgency goes beyond the loss of lives and displacement of people, experts say. Millions of children have seen their childhood maimed and their future puts at risk.
