When Holger Klein was 18, he reached a breaking point in the middle of another night of racing thoughts. Sleep had become impossible. Reading no longer helped, and even alcohol failed to calm the intensity inside his mind. In desperation, he opened a medicine drawer, swallowed whatever he believed might quiet the storm, and thought: it is quite possible I will die now.
The episode, he later recalled, marked a turning point. The next morning, he woke up alive and confronted a reality he could no longer ignore. He sent an email to his parents describing his crisis and soon sought therapeutic help. What followed would shape the trajectory of his life: a diagnosis of bipolar disorder, a condition once known as manic-depressive illness.
The story, published in Die Zeit, traces Klein’s journey through the shifting terrain of psychiatric diagnosis—how it can provide structure and relief, and yet gradually become a defining label that narrows identity and expectations.
At first, the diagnosis brought clarity. Bipolar disorder describes extreme mood swings between depressive lows and manic highs, sometimes accompanied by distorted perceptions of reality. For Klein, the explanation made sense of years of instability that had begun in childhood. Periods of withdrawal and exhaustion were followed by bursts of energy and fixation, moments when he would become entirely absorbed in new interests, only to abandon them weeks later.
Even as a child, he recalls cycles that seemed to arrive without warning. He would struggle to meet friends or attend school during low phases, then suddenly become intensely driven, animated by ideas that felt urgent and consuming. At one point, he spent all his pocket money on comic books, filling his room with stacked collections of Lustige Taschenbücher until the obsession passed and the books were eventually stored away in an attic.
Later in life, these cycles intensified. During his university studies in mathematics and physics, Klein experienced rapid alternations between high energy and deep exhaustion. He describes manic phases as resembling a chemically induced state of elevation, where confidence and momentum feel limitless, even as physical energy is depleted. In one such period, he recalls dancing alone in his room to techno music before going outside convinced that every glance from strangers confirmed his extraordinary self-worth.
But each high phase was followed by collapse. The lows were marked by paralysis, despair, and prolonged inability to function. Sleep disturbances became constant, either driven by overstimulation in manic states or emotional exhaustion in depressive ones. It was during this period, roughly three years before the interview reported in Die Zeit, that Klein’s crisis episode occurred and he first sought sustained psychiatric help.
The diagnosis of bipolar II disorder—characterized by less severe manic episodes than full bipolar I—offered him a framework that felt scientifically grounded and emotionally relieving. It also connected his experience to patterns he recognized in his family history, including relatives with unusual behavior, depression, and psychotic episodes. The sense that he was not alone, that his condition was understood and treatable, provided a stabilizing structure at a time of uncertainty.
Psychiatrists and researchers quoted in Die Zeit emphasize this function of diagnosis. As Anthony David and Quinton Deeley write in Psychological Medicine, the primary benefit of psychiatric classification is often the feeling of being understood, as well as the ability to connect personal experiences to a broader group of people with similar symptoms. Diagnosis, in this sense, creates coherence where previously there may have been only fragmentation.
For Klein, this initial clarity was significant. He describes reading about his condition, learning that it was recognized, and understanding that there were interventions available. The diagnosis gave him language and access to treatment, including structured medical and psychological support.
Yet over time, the same label that provided relief began to shape his self-perception in more limiting ways. As reported by Die Zeit, Klein describes gradually internalizing the diagnosis as a fixed identity. On difficult days, he began to interpret depressive episodes as predetermined states in which change was impossible. The expectation that moods followed an unavoidable biological pattern reduced his sense of agency, reinforcing passivity during low phases.
The effects were not limited to depression. In elevated states, he also experienced a diminished sense of restraint. If moods were seen as inevitable, then resisting them appeared pointless. The result, he says, was a growing tendency to surrender to extremes rather than actively moderating them.
This dynamic reflects a broader concern explored in the article: that diagnostic labels, while clinically necessary, can also be internalized in ways that reinforce stigma and limit recovery. Patients may adopt simplified narratives about themselves—such as being “sick” in a fixed, unchangeable way—which can reduce their perception of control over symptoms. Research cited in Die Zeit suggests that when individuals strongly identify with a biological explanation for depression, they may become more likely to believe they have little personal influence over their condition.
Over-identification with diagnosis can also shape expectations about the future. People who strongly define themselves by their condition may be more prone to interpret emotional fluctuations as permanent states rather than temporary experiences. This, in turn, can deepen feelings of helplessness and reinforce cycles of withdrawal or impulsive behavior.
In Klein’s case, this meant that both highs and lows became increasingly framed through the lens of inevitability. The label that once helped him understand his experiences began to structure them, narrowing the space for alternative interpretations of his emotional states.
The article in Die Zeit presents this tension without resolving it simply. Diagnosis, it suggests, is neither purely liberating nor purely restrictive. It can open doors to treatment, validation, and community, while also introducing a powerful narrative framework that can reshape identity itself.
Today, Klein reflects on this duality with ambivalence. The diagnosis was necessary for recognition and treatment, yet it also became something he had to consciously distance himself from in order to regain balance. His experience illustrates the paradox at the heart of psychiatric labeling: the same framework that explains suffering can, over time, begin to define it.
As Die Zeit reports, the broader question remains unresolved in medicine and mental health practice—how to preserve the benefits of diagnosis without allowing it to become a limiting identity. For those living with conditions like bipolar disorder, that balance can determine not only how illness is treated, but how life beyond the label is imagined.
