Eyes closed.

Breath steady.

Split apart from what you were-

Nearly ready to be what you are. — jann arden (@jannarden) December 29, 2018

In November 2017, Arden sat down with ET Canada’s Sangita Patel to promote her memoir Feeding My Mother, in which she chronicles her mother’s Alzheimer’s battle.

“There are those moments where she rises to the surface for me and tells me that it’s OK. And that I’m going to be OK. That I can do this. And that, you know, she’s doing the best she can,” Arden explained.
