You tell someone about something that happened and they look you in the eye and calmly say that you're making it up, that it never went like that, that you always blow everything out of proportion. At first you push back. Over time, you start to doubt your own memory. And one day you catch yourself apologising for things you don't even remember doing, convinced that you're the one with the problem. If this scene sounds familiar, you may have experienced gaslighting up close.
Gaslighting is a form of quiet manipulation that's hard to see from the inside, precisely because its goal is to make you doubt your own judgement. In this article I'll explain what gaslighting is, the tactics used by whoever practises it, how to recognize it and what you can do to rebuild trust in yourself.
What gaslighting is
Gaslighting is a form of psychological manipulation in which one person makes another doubt their own perception, memory or judgement. By denying facts, distorting conversations and questioning the way you see things, they get you to end up thinking you're the one who remembers wrong, who overreacts or who is 'not right in the head'. The American Psychological Association describes it as manipulating someone into questioning their own ideas about reality or even doubting their own sanity. It isn't a one-off argument: it's a sustained pattern that, drop by drop, erodes the trust you have in yourself.
Where the term 'gaslighting' comes from
The name comes from a 1938 play, Gas Light, and the films that were made from it afterwards. In the story, a husband manipulates his wife into believing she has lost her mind: among other things, he dims the gas lights in the house and, when she mentions it, insists that nothing has changed, that she's imagining it. Little by little, she stops trusting her own senses. That's where the lasting image comes from: to gaslight someone is, literally, to manipulate the other person's reality until they stop believing what they see.
How it works: the tactics of gaslighting
Gaslighting is rarely a shout; it's usually a steady drip. Whoever does it doesn't need to be right, they just need you to stop trusting your own view. To pull this off they use almost always the same moves, even if they aren't fully aware of it.
Typical phrases of someone who gaslights
- Denying the evidence: 'that never happened', 'you're making it up', even when you saw or heard it with your own eyes.
- Distorting what you remember: 'it wasn't like that', 'you remember everything backwards'.
- Minimising what you feel: 'you're exaggerating', 'you're too sensitive', 'it's not that big a deal'.
- Deflecting and blaming: they turn the conversation around until you're the one apologising.
- Questioning your mind: 'you're paranoid', 'you should get that looked at'.
- Hiding it behind affection: they pass it off as a joke or as 'I'm only saying this because I love you and I worry'.
Signs that you're being gaslit
Because gaslighting makes you doubt your very perception, it's often easier to recognize by how you feel than by what happens. It's worth paying attention if you identify with this:
- You doubt almost everything you remember and you've started noting things down or saving messages 'just in case'.
- You apologise constantly, even when you don't quite know what for.
- You come out of many conversations confused and drained, unsure who was right.
- You often wonder whether you're the one who's 'overreacting' or 'going crazy'.
- You find yourself justifying this person's behaviour to others.
- You notice you've gradually lost confidence and barely trust your own judgement any more.
Why it's so hard to notice
Nobody starts a relationship expecting to be gaslit. It usually creeps in, after a stage when everything felt intense and wonderful, and the person doing the manipulating is often exactly someone you trust: a partner, a parent, a friend, a boss. Because the wearing-down is slow and comes mixed with good moments, there's no clear day when you say 'this is abuse'. On top of that, the whole point of gaslighting is to make you doubt yourself, so your own tool for spotting it —trusting what you see— is precisely the one that gets damaged.
Where gaslighting shows up: partner, family and work
Gaslighting doesn't only happen in couples, though that's where it's talked about most. It shows up in toxic relationships, where it mixes with jealousy and control; in families, when a parent systematically denies what the other person remembers about their childhood; among friends; and at work too, when a boss or colleague makes you look incompetent by denying instructions they had given you. In the most serious cases, gaslighting is one of the tools of psychological abuse within gender violence.
The effects of gaslighting on mental health
Living under gaslighting for a long time takes a heavy toll. It's common to end up with self-esteem on the floor, with anxiety, depressive symptoms and a constant sense of moving through life with the handbrake on. Because the person makes you feel you can't rely on anyone but them, isolation and emotional dependence often appear too. The World Health Organization notes that psychological abuse, which gaslighting is part of, leaves deep and lasting consequences for mental health, not just physical.
Gaslighting or a simple disagreement?
Not every argument is gaslighting, and labelling everything that way doesn't help either. Two people can remember a conversation differently without anyone lying: memory is fallible. The difference lies in the pattern and the intent. In a healthy disagreement, the aim is to understand each other, and you can both accept that you may recall things differently. In gaslighting, by contrast, there's one side that repeatedly distorts reality to gain power and leave the other insecure. The APA places this manipulation within emotional abuse, not a simple misunderstanding. A clear clue: if you systematically feel worse about yourself and more insecure after talking to this person, something is off.
What to do if you're being gaslit
The first and hardest step is to trust yourself again. Start by trusting your perception: what you've seen and felt counts, even if it's disputed. It helps a lot to keep a record —note down what happened, save messages— so you have a point of reference when they make you doubt. Look for outside eyes: tell someone you trust who can say 'no, you're not making it up'. Set clear boundaries and don't get drawn into arguing every version of the facts, because that ground always favours the manipulator. And remember you're under no obligation to convince the person manipulating you: often the only healthy way out is to put some distance.
How to rebuild trust in yourself
Getting out of gaslighting, or moving away from it, is only the beginning; then comes the rebuilding. It's about learning to listen to your own judgement again and treating yourself with a little tenderness after a hard stretch. Practising self-compassion —talking to yourself the way you'd talk to a friend who's struggling— and gradually recovering your confidence through small decisions of your own help you rebuild the trust the manipulation had been taking from you. It doesn't happen in a few days, but it does come back.
When to seek professional help
Realising it's gaslighting is already a huge step, but undoing its effects on your own can be hard, especially if the relationship is still going or if it's left you badly shaken. It's worth seeking help when you notice you've lost confidence in your own judgement, when the anxiety or sadness won't lift, when you struggle to set boundaries or when you're in a relationship you don't know how to leave. Asking for help isn't a sign of weakness: it's reclaiming a space where what you feel is valid again.
How therapy helps
In therapy we work on gaslighting from the ground up: validating what you've been through again, understanding how it has affected you and rebuilding trust in yourself so that nobody gets to decide for you what's real and what isn't. Depending on the case, that means working on self-esteem therapy, emotional dependence or, if there has been abuse, more specific support. I do this in person in Igualada or with online therapy, in English, Spanish or Catalan, at your own pace.
If you've recognised yourself here, get in touch for a first assessment with no obligation. And hold on to this: if someone needs you to doubt yourself in order to be right, the problem isn't your memory; gaslighting is manipulation, and you have every right to trust what you see and what you feel again.
