Gaslighting victims are so uncertain about everything that happens in their lives that they are often too scared to make decisions. Every rational choice they make has been discredited or invalidated by the gaslighter, so they have the impression that they are unable to make a good decision.
When a person endures gaslighting for a long time, you will begin to notice changes in his personality, behavior, and manners. The changes can be subtle, but become surprisingly obvious once they think about who they were before the arrival of this toxic manipulative person in their lives.
Constant state of confusion
Gaslighting victims have had all aspects of their lives challenged, so they have a hard time believing in them. They doubt their thoughts, so their natural instinct fails to make an impact on sound decision-making. The gaslighter uses the constant state of confusion of the victim to control it.
Victims often know that something is wrong, but they have trouble understanding what it means.
They feel isolated
When a person has undergone gaslighting, they begin to isolate themselves from the world around them simply because they feel alien to themselves. She can not socialize normally anymore because she feels safer alone than with anyone else.
This is exactly what the abuser wants: to isolate this person enough so that they do not ask for help from another person in their life.
