According to the merriam webster online dictionary, self
definition is "the evaluation by oneself of one's worth as an individual." Merriam Webster doesn't take into account the opinions or feelings of others and neither should you. Star Jones' momma says "You're the author and editor of the only dictionary that defines you."
Believe in yourself. Value yourself. Love yourself. Be who God has called you to be. You are loved. You are worthy. You are more than enough. You are destined and called to do great things. Keep God first. Stay prayed up my loves.
