"Everything is not perfect": Michelle Williams on mental health and her new book, "Checking In"

Grammy-winning singer-songwriter Michelle Williams is getting candid about her journey with depression and prioritizing mental health in her memoir "Checking In: How Getting Real About Depression Saved My Life — and Can Save Yours." She opens up about suicidal thoughts; the importance of her faith, family and friends; and the lessons she's learned about prioritizing her mental health.

"Everything is not perfect," William said in an interview on CBSN. "And that is OK." As a longtime advocate for mental health, the Destiny's Child band member urges people to understand the importance of "checking in" with themselves, with God, and with others — a journey that is not a "one-and-done" thing, but a tool a person can utilize daily.
