Psalm 139 v 13-16 says
For you created my inmost being;
    you knit me together in my mother’s womb.
14 I praise you because I am fearfully and wonderfully made;
    your works are wonderful,
    I know that full well.
15 My frame was not hidden from you
    when I was made in the secret place,
    when I was woven together in the depths of the earth.
16 Your eyes saw my unformed body;
    all the days ordained for me were written in your book
    before one of them came to be.

God spent a long time creating you
And God doesn't make worthless things

So ........ believe the truth about yourself
Not from what your parents told you
Not from what your friends or enemies tell you
But know your value from God's perspective because that is truth
And then live each day from the foundation of that truth
Knowing the gifts that God has put within you
And faithfully using those gifts for His purposes
As He gives you opportunity
