Keep in mind that every individual is unique, and not all INTJs will respond the same way, but some common signs might include:
Withdrawal: INTJs are known for their introverted nature, but when they are in a dark place, they may withdraw even further from social interactions and isolate themselves.
Increased Criticality: INTJs are naturally critical thinkers, but when they are struggling, they may become excessively self-critical and critical of others, leading to a negative outlook.
Loss of Enthusiasm: INTJs typically have a strong sense of purpose and passion for their interests. In a dark place, they may lose enthusiasm and interest in things that usually engage them.
Emotional Suppression: INTJs are not naturally emotionally expressive, but in a dark place, they may suppress emotions even more, leading to feelings of emotional numbness or detachment.
Extreme Perfectionism: INTJs often strive for excellence, but when in a dark place, they may become fixated on perfection to an unhealthy degree, leading to high levels of stress and frustration.
Lack of Focus or Decision-Making Difficulties: When struggling, an INTJ may find it challenging to concentrate or make decisions, which can exacerbate feelings of frustration and helplessness.
Overwhelmed by Emotions: INTJs are typically more logical than emotional, but in a dark place, they may find themselves unexpectedly overwhelmed by emotions they struggle to process.
Neglecting Physical Needs: INTJs might neglect their physical well-being when they are in a dark place, such as not eating well, not exercising, or not getting enough rest.
Increased Cynicism: While INTJs can be naturally skeptical, in a dark place, they may become excessively cynical and pessimistic, seeing negative outcomes in almost everything.
Difficulty Expressing Needs: INTJs may find it hard to express their emotional needs to others, leading to a sense of isolation and loneliness.
It is essential to remember that everyone experiences difficult times in life, regardless of personality type. If you notice signs of someone, including an INTJ, being in a dark place for an extended period or showing significant distress, it is crucial to offer support and encourage them to seek help from mental health professionals if needed.
