insecurity

Insecurity is a feeling of uncertainty, a lack of confidence or anxiety about yourself. Put aside your insecurities and start acting like the smart, capable person you are!

Insecurity is the word for what you are probably feeling when you walk into the cafeteria on your first day at a new school and everyone else already has someone to sit with. But soon you will make friends and forget about your insecurities. It can also describe the state of being open to danger or threat. The economy may have you worried about job insecurity. Or maybe it's the insecurity of a rocky relationship that keeps you up at night.
