Japanese artist Yayoi Kusama is known for her polka-dot art. She has been open about her mental health and shred that art has become her way to express her mental problems. In her words "I fight pain, anxiety, and fear every day, and the only method I have found that relieved my illness is to keep creating art."
I feature her in my upcoming book Artpreneur when I talk about embracing your inner weirdo. Many artists suffer from anxiety and it's one of the reasons that I have mental health experts on the podcast.
