Walking through his own ashes: the straight-A student who lost 18 years and came back a doctor

Andrew Mwengwa Githuka was the kind of student teachers remember.

Eighty-two points in the Kenya Certificate of Secondary Education (KCSE), a straight A, the sort of result that opens doors and settles a family's hopes. The future looked certain.

It did not arrive on schedule.

Long before the exam results, the unravelling had already begun. Mwengwa traces it back to Standard Seven, to the first cigarette, an ordinary act of experiment that most boys leave behind.

He did not. Cigarettes gave way to alcohol, then cannabis, then inhalants, then injectable drugs, each step deeper than the last. By the time he understood what he was fighting, nearly two decades were gone.

Eighteen years. Careers his classmates built, milestones they passed, a life that moved on without him.

Recovery, when it came, was not a single moment but a long walk back. He sought help. He got clean. He returned to the classroom he had left as a gifted teenager, this time as a man carrying the weight of everything he had lost.

Twenty-two years after finishing secondary school, he graduated as a medical doctor.

That arc, from ashes to a medical degree, gives his book its title. Walking Through My Own Ashes chronicles the descent, the lost years and the resolve that pulled him out. Its launch, though, became something larger than a book event.

The room filled with people who recognised the story as their own. Former addicts spoke of careers delayed, families broken, marriages stalled and finances hollowed out before recovery found them. Parents described the particular anguish of watching a child sink, and the quieter joy of watching one climb back.

Into that gathering, Deliverance Church Thika Bishop Kennedy Mbatia offered a challenge.

The fight against drug and substance abuse, he said, cannot be left to families, churches or the government alone. He called on communities, institutions and faith-based organisations to share the work of prevention, rehabilitation and the reintegration of those trying to rebuild.
