What does insecuirity mean and how does it affects

you feel insecure when you are uncertain if you are good enough for something. for example, if you are uncertain whether you are smart enough to join an honors program, if you are attractive enough for other people to be interested in you, or if you are funny enough for people to want to spend time with you. the abilities that feel you lack are of the kind that are judged and affirmed by other people. the abilities that other people care about largely depend on your social circle. for instance, in a professional environment people may care much less about your looks, and more about your business competences (unless you work in modeling). because insecurity is about being good enough in or at something for other people, the emotion is ultimately a fear of not being accepted, respected, or popular.
