The actress has spoken candidly of her experiences with depression and even wrote a book, Down Came the Rain: A Mother's Story of Depression and Recovery.
The Harry Potter author revealed in an interview that she had once been so depressed that she considered suicide.
The singer has suffered from depression for most of her life: "I grew up in the presence of melancholy, a feeling of loss over things that maybe I don't have or never had. It is a shadow for me. It's constantly there. I just know how, at this point, to sort of manage it."
