Gaslighting is a form of psychological manipulation in which one person causes another to question their own reality, memory, perceptions, or sanity. The term originates from the 1944 film Gaslight, in which a husband systematically manipulates his wife into believing she is losing her mind. While gaslighting can occur in any type of relationship, it is most commonly studied in the context of intimate partnerships, family systems, and workplace dynamics.

Gaslighting rarely begins suddenly. It tends to escalate over weeks, months, or years, which makes it difficult for the person being targeted to recognize it. Common signs include:

• Chronic self-doubt. You frequently question your own memory of events, your emotional reactions, or your competence, even in areas where you were previously confident.
• Confusion and disorientation. You feel foggy or unable to think clearly. You may struggle to articulate what is wrong, even though you sense something is off.
• Constant apologizing. You find yourself saying sorry for things that are not your fault, or you feel responsible for the other person's emotional state.
• Minimizing your own feelings. When you try to express hurt, you are told you are being "too sensitive," "dramatic," or "crazy," and you begin to believe it.
• Denial of your reality. The other person flatly denies events you remember happening, insists they said something different from what you recall, or claims you are imagining things.
• Erosion of identity. Over time, you may feel you have lost a sense of who you are. Activities, opinions, and friendships that once defined you start to fall away.
• Isolation. The gaslighter may discourage or sabotage your relationships with others, leaving you more dependent on them for validation.
• Feeling like you are "going crazy." This is one of the most commonly reported experiences among people who are being gaslighted.

Gaslighting can co-occur with other forms of emotional abuse, including verbal aggression, controlling behavior, and withholding affection or resources. The psychological effects can be severe, including anxiety disorders, depression, post-traumatic stress, and lasting difficulties with self-trust.

Gaslighting is not a clinical diagnosis in the DSM-5 or ICD-11. It is a recognized pattern of psychological abuse that falls under the broader category of coercive control. Because it operates through subtle, repetitive interactions rather than a single dramatic event, it can be difficult to identify from the outside, and even harder to name when you are experiencing it.

How gaslighting is identified. Mental health professionals assess gaslighting by exploring a person's relational history, emotional symptoms, and patterns of self-doubt. There is no single lab test or diagnostic tool. Instead, clinicians look for consistent patterns: a relationship in which one person's version of reality is systematically invalidated by another, leading to measurable psychological harm. Validated research instruments such as the Gaslighting Questionnaire and assessments of coercive control can support this process.

Who is at risk. Anyone can be gaslighted, regardless of intelligence, education, or strength of character. However, certain factors can increase vulnerability. People with a history of childhood emotional neglect, those who tend to prioritize harmony in relationships, and individuals in relationships with significant power imbalances (such as an employee and supervisor, or a person who is financially dependent on a partner) may be at greater risk.

Recovery and treatment. Recovery from gaslighting focuses on rebuilding trust in one's own perceptions and restoring a stable sense of identity. Common therapeutic approaches include:

• Individual psychotherapy. Cognitive behavioral therapy (CBT) and trauma-focused therapies can help a person recognize distorted thinking patterns that were introduced through gaslighting, and replace them with accurate self-appraisals.
• Psychoeducation. Learning about the specific tactics of gaslighting, such as denial, diversion, trivializing, and countering, can be profoundly validating. Many people report that simply naming the behavior reduces its power.
• Safety planning. When gaslighting occurs within a context of domestic abuse, a therapist or advocate can help develop a plan for physical and emotional safety.
• Rebuilding social connections. Reconnecting with friends, family, or support groups helps counter the isolation that gaslighting creates and provides external reality checks.

Recovery is not always linear. It is common to cycle between clarity and self-doubt, especially in the early stages. A skilled therapist can serve as a steady, validating presence during this process.

If you recognize yourself in several of the experiences described on this page, reaching out for professional support is a reasonable and important step. You do not need to be certain that gaslighting is occurring before you ask for help. A qualified therapist can help you sort through confusing relationship dynamics in a nonjudgmental environment.

Seek help promptly if you:

• Feel persistently confused about what is real in your relationship
• Have noticed a significant decline in your self-esteem or sense of identity
• Are experiencing symptoms of anxiety, depression, or post-traumatic stress
• Feel afraid of your partner, family member, or another person in your life
• Have become increasingly isolated from friends and family
• Feel trapped or hopeless about your situation

If you are in immediate danger, contact emergency services (911) or the National Domestic Violence Hotline at 1-800-799-7233. You can also text START to 88788 or chat online at thehotline.org.

Remember: questioning whether your experiences are "bad enough" to deserve help is, in itself, a common effect of gaslighting. You deserve to be heard and believed.
