Gaslighting is a form of psychological manipulation where a person makes a victim doubt his/her own sanity, making them question their reality, perception and judgment.
Someone trying to gaslight you might:
Tell blatant lies
Openly deny words and actions, even when you have proof
Use what is dear to you as a weapon
Exhaust your energy and confidence over time
Use confusion to weaken you
Use positive reinforcement to control you
Try to turn people against you
Tell everyone that you are crazy
Try to make you believe that the entire world is lying
Recognize the pattern of belittling behavior. Gaslighting is effective only when the victim isn’t aware of it. Once you understand the pattern, it’ll be easier to fight it.
