[Q]: Watch CBN News' Heather Sells interview with  Sadie Robertson  about  her  latest book and what's next for  her .
 Sadie Robertson  is well known for  her  captivating smile and role in the reality TV series "Duck Dynasty"
The show ended last year but the 20 year-old continues to make a name for  herself .  She  has acted in God's Not Dead 2  danced  her  way to first runner up on Dancing with the Stars  and continues to inspire fans and share  her  faith on YouTube.
Now  she 's traveling the world and sharing how  she  learned how to conquer fear in  her  new book  "Live Fearless."
"I used to live in a lot of fear. I had a lot of anxiety and really dealt with panic attacks - the whole nine yards. Anything fear  I was totally living in it. It was actually in the season of my life when I was very  very public  " Robertson  told CBN News. " I don't feel like people were really seeing the fullness of who I was because I was so afraid."
Despite  Robertson 's life being so public   she  was engaged in a very private war against fear for years until  she  learned how to beat it.
"Finally  I found freedom through my faith and totally over fear. All of a sudden  I become a totally different person. I start speaking all of a sudden. I'm a lot more confident in what I'm saying. I have a lot more life  more joy-filled  and people started to see the change in me "  she  said.
 Robertson  says one of the biggest ways to fight anxiety is to take every fearful thought into captivity.
"You can be in like  literally  a room where there's no fear around you but because your mind is so consumed with fearful thoughts. It's really a mind thing. And so  really finding freedom and captivating the thoughts of your mind is a huge way out of it "  she  shared.
 Robertson  wrote this book for anyone who struggles with fear like  she  did.
 Robertson 's life hasn't shown any signs of slowing down since  she  wrote  her  book.  She  recently completed  her  "Live Original Tour" which brings thousands of young people together to worship God and learn how to live as He created them to be.
