How can we use Instagram and Facebook without doing ourselves harm? In the last episode of the series, Fearne speaks to social media mentor - and Fiit fitness trainer - Chessie King.    The pair speak about their own battles online, and how Chessie's managed to take on the trolls... and win.    Our sponsor for this episode was Fiit - to find out more about them head to https://fiit.tv/blogs/get-fiit-with-fearne/.    We'll be back with new episodes very soon - in the meantime, why not leave us a review on Apple Podcasts?
