Early in life, individuals develop an internalized view of themselves as adequate or inadequate within the world. Children who are continually criticized, severely punished, neglected, abandoned, or in other ways abused or mistreated get the message that they do not 'fit' in the world -- that they are inadequate, inferior or unworthy.
Such feelings of inferiority are the genesis of low self-esteem.
Individuals with low self-esteem become overly sensitive and fearful in many situations..
They are afraid they won't know the rules or that they've blundered, misspoken or acted in ways others might consider inappropriate. Or they might perceive that others reject or are critical of them.
Once low self-esteem is formed, the person becomes hypersensitive -- they experience "self-esteem attacks" that take the form of embarrassment or shame.
Unlike guilt -- which is the feeling of doing something wrong, shame is the feeling of being something wrong. When a person experiences shame, they feel 'there is something basically wrong with me.
This is a common emotional response in adult children of alcoholic parents, as well as those who grew up with depressed parents, abuse, religious fanaticism, war, cultural oppression, or adult or sibling death. All of these experiences cause an individual to feel vulnerable, helpless and shamed.
