INSECURITY FEELING
A person who is insecure lacks confidence in their own value, and one or more of their capabilities, lacks trust in themselves or others, or has fears that a present positive state is temporary, and will let them down and cause them loss or distress by "going wrong" in the future. This is a common trait, which only differs in degree between people.
This is not to be confused with humility,which involves recognizing one's shortcomings but still maintaining a healthy dose of self-confidence. Insecurity is not an objective evaluation of one's ability but an emotional interpretation, as two people with the same capabilities may have entirely different levels of insecurity.
Insecurity may contribute to the development of shyness,paranoia and social withdrawal, or alternatively it may encourage compensatory behaviors such as arrogance,aggression,or bullying , in some cases.
The fact that the majority of human beings are emotionally vulnerable, and have the capacity to be hurt, implies that emotional insecurity could merely be a difference in awareness.
Insecurity has many effects in a person's life. There are several levels of it. It nearly always causes some degree of isolation as a typically insecure person withdraws from people to some extent. The greater the insecurity, the higher the degree of isolation becomes. Insecurity is often rooted in a person's childhood years. Like offense and bitterness, it grows in layered fashion, often becoming an immobilizing force that sets a limiting factor in the person's life. Insecurity robs by degrees; the degree to which it is entrenched equals the degree of power it has in the person's life. As insecurity can be distressing and feel threatening to the psyche, it can often be accompanied by a controlling personality type or avoidance, as psychological defense mechanisms.
Insecurity can be overcome. It takes time, patience and a gradual realization that one's own worth is purely a matter of perspective (or subjective opinion of oneself), and so while it may be true that insecurity can follow from concerns relating to objective reality, this is by no means a necessity, but more a tendency.The first of Erikson's stages of psychosocial development details the challenge of finding security and learning to trust oneself and one's environment.
