When you suffer from anxiety, the mix of emotions you're bombarded with on a daily basis can sometimes feel overwhelming.
"I needed to make something positive out of a negative experience," she tells The Huffington Post UK.
"I think images are a powerful tool to access the emotions. And somehow I knew that my experience with anxiety had something universal, even if what I share is really personal."
Lepage says her energy levels often have an impact on her anxiety.
"When I’m tired, I tend to be more anxious. When that happens, everything seems harder to do," she says.
"I feel I won’t be able to make it through the day. Everyday tasks weigh a ton on my shoulders. But it happens less and less because I am aware of what triggers my anxiety. And when I get anxious, I know it won’t last forever."
When she feels stressed, Lepage has one coping mechanism she says helps calm her emotions.
"When I realise that I’m stressed I smile," she says.
"You cannot smile if you're holding a lot of tension in your face. You have to relax to be able to smile. Of course, that won’t work in the middle of a panic attack."
