She said sharing her experience is part of her healing journey and she expressed the hope that her story can help others. Today, Oct. 3, we spoke with Andrea Clark from Postpartum Support International, who called Mariah's post an 'incredibly brave thing to do.' She also suggested that Mariah's status as someone who is well known adds to the power of the message. "No matter whether you are upper class, middle class or economically disadvantaged," said Clark. In her Instagram post, Mariah says that if she can help just one person, sharing her story will be worthwhile.
