Gaslighting is making someone doubt their own memory, perception, or sanity. It sounds like 'That never happened,' 'You're too sensitive,' or 'You're remembering it wrong.' Repeated over time, you stop trusting yourself and start deferring to their version of reality. If you keep leaving conversations more confused than when they started, that disorientation is the tactic working — not a flaw in you.
Gaslighting attacks the one tool you'd use to check reality — your own perception. That's why victims often feel like they're 'going crazy.' You're not; you're being destabilized on purpose.
Writing down what happened soon after, and checking it against a trusted friend, helps you anchor to your own memory again. Self-trust is the antidote.
