Dealing with gaslighting involves recognizing the manipulation, trusting your perception, and setting boundaries. First, educate yourself about gaslighting tactics and how they work. Trust your instincts and feelings; don't doubt yourself. Maintain a support system of friends, family, or professionals who validate your experiences.

Establish clear boundaries with the person gaslighting you. Communicate calmly but firmly that you won't tolerate their behavior. Keep a journal of incidents to help you stay grounded in reality and counter their attempts to distort the truth.

Practice self-care and prioritize your mental well-being. Engage in activities that boost your self-esteem and reduce stress. Consider seeking therapy or counseling to gain guidance and coping strategies. If the gaslighting continues in an unsafe environment, it might be necessary to distance yourself from the individual or seek legal protection.

Remember, you have the right to your feelings and perceptions, and no one should undermine your reality.
