Gaslighting is manipulation and psychological control. If you are being gaslighted, someone is deliberately and systematically giving you false information that leads you to question what you know is true. You may end up doubting your memories, perception, and even your sanity! Gaslighting can occur in personal or professional relationships, and the victim’s identity and self-worth are targeted. Manipulative people who engage in gaslighting often want to control their victim emotionally, physically, or financially.
