Everyone has a point in their teenage life where they question themselves or have a low self-esteem. It's not something you can just take. It's an emotional/mental feeling when you know that you are okay being you and know what you're worth. Today, studies show that self-consciousness is found mainly in the circumstances of:
1)Family
2)Friends
3)Peers/School

To know if you have a high self-esteem, you must have these "senses":
1) A sense of security.
-feeling safe at home, school, and your neighborhood
2) A sense of belonging.
-feeling connected and accepted by others (family, classmates, etc.)
3) A sense of competence.
-doing things that make you feel confident, in control (drawing, singing, etc.)
4) A sense of who you are.
-not easily swayed by others, no peer pressure, accepts responsibility of what you do, and know what you're limits are
5) A sense of purpose.
-have your own goals and power to see them through (what makes you happy and fills you with passion; fulfillment)
