Her way of dealing with her mental state is mindfulness: learning to connect with your body when your mind is driving you somewhere you don't want to go. Also, she suggests that we are kind to our thoughts. I would say befriend our thoughts.
I often go on about this, but I think it's vital. As a practice, when you hear your mind criticising, instead of getting lost in its thoughts and feelings, take it as a sign to reconnect to your body.
Put your focus on sensing physical sensations somewhere, for example you feet. This way, instead of being an enemy of your thoughts, you befriend your mind.
