To me, having a mental health issue means something more than dealing with a diagnosable illness.
It's all about maintaining the right quality of life, protecting yourself from disease and not having to fear that death is at your door.
If we were to expand the definition of mental illness in such a way, then the continent of Africa is suffering yet another epidemic - only this one is of the mind.
It's mental disease brought on by the scourge of AIDS that, despite medical advancements, is still killing hundreds of thousands of people each year.
At the same time, it's turning hundreds of thousands of children into orphans, as well as many others motherless and fatherless every day because of the deadly disease.
In the wake of their dead loved ones, many are suffering from witnessing the spectacle of people who once led robust lives only to be destroyed by a disease that took their life away long before they were dead.
The story revolves around Haregewoin Teferra, an Ethiopian woman who has welcomed people of all types - particularly youthful victims of AIDS, many of them orphaned - into her house to talk, eat and, usually, stay for a while until they seek stability, care and love.
In the opening scene, Haregewoin got a call about an abandoned child. She was inundated with children already. But the mother had AIDS and the dad, TB.
No, she said initially. But Haregewoin quickly changed her mind. Over and over again, Haregewoin's objections almost always disappear after some reflection. To Haregewoin, humanity always triumphs over convenience.
This is what happens in Ethiopia, where disease has forced a population that once lived in civility to lean on others - even if they're sick, too - for support. It was under colonial rule but broke free from the Italians in the 19th Century, largely because people felt proud about their country and their leadership.
Dictators took over and selfishly raped the landscape for their own benefit, Greene noted. The rest of the hard-working country suffered as hunger, poverty and lack of education all soared. Places that were once lush with forests and other resources were suddenly deprived of water and oxygen.
Greene, who lived the life of a soccer mom, read about this situation in The New York Times and wanted to do something about it. She eventually found herself with a book contract, and then flying to Ethiopia to watch Haregewoin do her work and see the sides of her that were truly heroic yet deeply human.
Haregewoin didn't even like talking about herself. She was too distracted by the children she had to save.
One boy, named Misty, was removed from his dad after he was constantly promised that he would be able to bring biscuits to him later on, but there was no follow through. He had to stay with Haregewoin and the taxi driver who brought him to Haregewoin's compound, and he did his best to calm him down despite the boy's cries of panic.
Haregewoin had lived the middle class life, too, only to see it disappear because of the epidemic.
She married a man named Worku and they had two children - not 20, like the family she came from. Haregewoin worked for a computer company and Worku was a high school principal, so they were educated, and they didn't want to go down the same path of living with a too-large family in a too-small house.
Then Worku surprisingly died of a heart attack - even though he appeared to be healthy. Soon after, one of Haregewoin's two daughters rebelled, got together with a security guard who acted thug-like, but still ultimately married her.
Haregewoin had a sudden back problem that she thought was cancer, so she went to Cairo to get it checked out. It turned out to be no big deal, but she liked Cairo and stayed - despite being far away from her family while it was falling apart.
Haregewoin started to worry when her daughter, in telephone conversations, complained about feeling tired. It turned out she was pregnant, but her complaints persisted. Hargewoin finally went to visit and found her somewhat emaciated, but she just thought it was because of the pregnancy.
Her daughter had the baby, and everybody celebrated. But the daughter became more of a recluse, and her husband put up a barrier between Haregewoin and her daughter that prevented Haregewoin from knowing too much.
Frustrated with the situation, Haregewoin eventually went to visit again, and found her daughter suffering from what appeared to be AIDS.
Haregewoin's son-in-law, Ashibr, took the baby away; Haregewoin cared for her daughter at a hospital and, later, at home, where she died in 1998.
Haregewoin was devastated. She went into seclusion, shunned people and thought about becoming a full-time mourner.
Only a religious group stood in her way, and asked her to take care of two teenage children. Haregewoin intially didn't think she could do it, but she did it - much to her friend's dismay - because she couldn't say no.
The children were rebellious - especially Abel, who was a drug addict. Those children were eventually taken away. But Haregewoin's willingness to take them in inspired religious groups to seek her help again. Other smaller children were dropped off, and the emptiness Haregewoin felt after losing her daughter quickly disappeared.
Virtually all the children had parents with AIDS or had died of AIDS. There were twins; there were even children with AIDS. One mother dropped off her baby, fell down and died just outside Haregewoin's door as she left. Even the police dropped off unnamed, abandoned children.
Haregewoin saw this as her calling - and even hung a picture in her house of her deceased daughter holding her newborn child with an inscription from a pop song: "There is no me without you."
The children, meanwhile, played in the yard and with each other, and then went to school and played soccer. One man dropped off his sick daughter just so she could socialize.
A group dropped off a young girl who hated being there, and wanted to prove it so badly that she repeatedly slammed Haregewoin's steel door, trying to get out. People on the other side of the door - the people who dropped her off - were crying. The author, who witnessed this scene, thought of offering the group money, but decided against it.
There were other troubles, too, that had nothing to do with disease.
An uncle Oscar who was involved in the life of a pair of twins came around, and Haregewoin blocked the door. Before this encounter, Oscar once pulled down the pants of one girl, and tried to rape her. He was caught, and he took off the hills. But he tried to re-enter their lives, and Haregewoin wouldn't allow it.
Overall, Haregewoin enjoyed the experience. But eventually, it took its toll. People in the area shunned Haregewoin and her children. They didn't want to come into contact with people who have had some association - even remotely - with AIDS.
Money was tight, and Haregewoin began taking donations. She told people she couldn't take any more children, but she did anyway, because she couldn't say no.
Children like Minty held out hope their parents were still alive. Minty, for instance, was hording rolls that he wanted to give to his father - even as they grew moldy and disgusting. He still wanted to give them to his dad, Eskender.
But Eskender, Haregewoin soon found out, died.
Haregewoin eventually grew weary. She saw her numbers grow from two dozen to three dozen children. She told people, "No more," but they came anyway.
Suddenly and hopefully, adoption groups approached Haregewoin. It was just the right time, because Haregewoin couldn't be the mother she was when she had fewer children.
She also needed a doctor - and she found one, an American who gave up his life for this cause. He examined a baby who was literally "dropped" at Haregewoin's house, and whom everybody thought had AIDS. The doctor discovered he actually had a milk allergy. He was given soy milk and became a normal, everyday child.
Adoption agencies eventually came out of nowhere, taking away babies left and right. Haregewoin grew attached to some of the children and didn't want to give them up. But she relented, realizing that others could provide a better life.
Haregewoin found a place for the older kids, too - the Americans, who had set up a local agency that found parents for the children.
A rich woman had a birthday party at Haregewoin's compound. She wanted her pampered child to see poverty. For a day, everybody - including Haregewoin - felt like they were in the middle of a fairy tale.
Haregewoin eventually developed something of a celebrity status in Ethiopia. She won an award that earned her a trip to the United States, the same country that provided shelter to companies who refused to allow generic anti-AIDSs drugs to be developed and cheaply sold and used in Africa, Greene noted
For Haregewoin, however, success didn't come without new struggles.
People started to resent her, and believed that she was getting rich off her good work. They started to snipe at her. An agency was upset with the way she handled the adoption of a girl who was presented by a 17-year-old mother. When the 17-year-old took the child back after much wrangling, the government investigated Haregewoin for child trafficking.
An investigation into a possible rape at Haregewoin's compound lingered for months as rumors began to spread about mistreatment and child-trafficking. Donations and adoptions stopped coming. The children were getting smaller meals.
Ultimately, Haregewoin was arrested and locked away, like she was a political prisoner. Her surviving daughter and friends tried to spring her loose, but Haregewoin viewed her time away as an opportunity. It gave her some moments to reflect, as though God led her here.
In early 2006, Haregowein was back home. The Ministry of Justice took over control of her orphanage, and also cleared Haregewoin of any wrongdoing.
She also reacquainted herself with her grandson, then 7. Ashibr relented after prodding from Haregewoin's surviving daughter. They developed a regular relationship, all while Haregewoin continued taking kids in.
But it was her time in jail that gave her the moment to realize her work was her gift to life.
