DISORDER GUIDES, EXPLAINED
Nine disorder guides, explained without shortcuts.
Plain-language guides to major depression, bipolar disorder, the anxiety disorders, OCD, PTSD, schizophrenia, schizoaffective disorder, and ADHD: what each pattern looks like, how clinicians recognize it, how treatment usually helps, and when to seek help promptly.
These guides describe patterns clinicians look for — not a diagnosis of any reader. A label is a map, not the person: two people with the same diagnosis can look very different, and only a clinician who knows your history can say what a pattern means. If you recognize yourself in one of these guides, treat that as a reason to start a conversation with a professional, not as a conclusion.

Mood disorders
GUIDE 01Major depressive disorder Major depressive disorder is more than a bad week or ordinary grief. It is a sustained state — at least two weeks — in which mood, energy, interest, sleep, appetite, and thinking shift together and begin to interfere with work, relationships, and self-care. It is common, it is not a character flaw, and it is treatable.Read the guide
GUIDE 02Bipolar disorder Bipolar disorder is a condition of mood episodes: periods of depression and periods of mania or hypomania — elevated, expansive, or irritable mood with unusually high energy. Between episodes, many people return to their usual selves. The pattern, not any single day, is what defines it.Read the guide
Anxiety, obsessive-compulsive, and trauma-related disorders
GUIDE 03Generalized anxiety disorder Generalized anxiety disorder is worry that will not switch off: excessive anxiety about everyday things — health, money, work, family — on more days than not for at least six months, experienced as hard to control. It is different from being a careful person; the worry itself becomes the burden.Read the guide
GUIDE 04Panic disorder Panic disorder is built around panic attacks: sudden surges of intense fear that peak within minutes, with a racing heart, shortness of breath, trembling, or a feeling of unreality or impending doom. The disorder itself is the pattern that follows — persistent worry about the next attack, and avoidance of the places where one might strike.Read the guide
GUIDE 05Obsessive-compulsive disorder Obsessive-compulsive disorder involves obsessions — intrusive, unwanted thoughts, images, or urges that cause anxiety — and compulsions, the repetitive behaviors or mental acts performed to neutralize that anxiety. Everyone has intrusive thoughts; in OCD they stick, demand rituals, and can consume hours a day.Read the guide
GUIDE 06Post-traumatic stress disorder Post-traumatic stress disorder can develop after experiencing or witnessing a traumatic event — violence, combat, a serious accident, disaster, or assault. The nervous system stays on guard long after the danger has passed: memories intrude, the body startles, and life quietly reorganizes around avoidance. It is an injury of memory and alarm, not a failure of toughness.Read the guide
Psychotic disorders
GUIDE 07Schizophrenia Schizophrenia is a disorder of perception, thinking, and motivation that usually emerges in late adolescence or early adulthood. Its core feature is psychosis — a loosened grip on shared reality — but it is more than psychosis: it also affects drive, expression, and cognition. It is a brain disorder, not a split personality, and it is not caused by bad parenting.Read the guide
GUIDE 08Schizoaffective disorder Schizoaffective disorder sits at the meeting point of schizophrenia and the mood disorders: psychosis — delusions or hallucinations — occurs alongside major mood episodes of depression or mania, and, crucially, psychosis also appears on its own, without mood symptoms, for at least two weeks. That independent stretch of psychosis is what distinguishes it.Read the guide
