As Mamush gradually began to lose his vision, school became more and more difficult. He could no longer read the blackboard or his textbooks. With no improvement in his vision nor any indication of receiving treatment, he was forced to drop out of school at grade 3.
Within a year of leaving school, Mamush faced more hardship. His father died, leaving his mother and younger siblings in his care. As the first born, Mamush was expected to handle the farm and lead the household. Being expected to deal with these sudden changes and new expectations was even harder with his deteriorating vision.
After 12 years of living in darkness, no one believed Mamush would ever regain his sight. Yet even though each day was a challenge, he somehow continued to help with the farm, and support his mother and siblings.
