An insecure woman seeks constant reassurance that she is beautiful, valued and loved. This is why you find insecure people to be such attention seekers. They are looking for validation that they are acceptable as they are.
Narcissists are afraid of life. They are afraid of being vulnerable therefore they take the most destructive way to gain control and power. They hurt people to make themselves feel better, strong and superior. They try to control and dominate others because its distracts them from dealing with their own issues.
Indeed. You know what insecure is? Not allowing your boyfriend to watch certain movies because there's hot chicks (For example, MILA KUNIS) and then when he watches it freaking out because you're sorry you don't have the perfect body like her and want to break up because of it... THAT is insecurity. Ha
