Become your own cheering section. Support and believe in your own choices as you grow into your best self. Refuse to alter your behavior to fit the expectations of others. You are good and right and acceptable in the eyes of those who love you and in the eyes of God. Accept yourself as you are, and behave in ways that validate you. As you develop confidence in your own worth you will no longer need others to validate you. When you know you have not compromised your own values and or tried to change yourself for others, you will gain confidence in yourself and become your own best advocate.
Act with self-confidence in your own actions and personhood and acceptance of yourself.
Develop your sense of self-worth and believe in it.
Know that you are no less valuable and important than anyone else.
Take into your soul the knowledge that you matter and have value to those who love you and to the Spirit that loves us all.
