Brittany was diagnosed with terminal brain cancer in January this year. She and her family moved from California to Oregon, one of only five states in the US that allow assisted dying by law, so that she could choose to have control over the end of her life.

Having met the criteria for Oregon’s Death with Dignity Act she was given prescription drugs which she can self-administer to die peacefully and painlessly at any time of her choice.

Originally she chose November 1st, two days after her husband's birthday, but in a newly released video she reveals that she doesn't want to be constricted by a particular date, although "it will come" because she can feel herself "getting sicker."

"But I still get out and do what I can, walking with my husband and my dogs, and things like that give me the greatest feelings of health I have these days."

Brittany has been working with Compassion and Choices to campaign for the right to assisted death, and made a heartbreaking video that went viral earlier this month about her choice. Since then, she has traveled to the Grand Canyon for the trip of a lifetime with her family, supported by, in her own words "the kindness of Americans around the country who came forward to make my bucket list dream come true."

In the new video, Brittany speaks tearfully about how she feels for her mother Debbie and husband Dan, who are set to lose a beloved family member. "Having been an only child for my mother I want her to recover from this and not break down or suffer from any kind of depression."

"My husband is such a lovely man and I understand everyone needs to grieve but I want him to be happy and I want him to have a family. I know that sounds weird but there's no part of me that wants him to live out his life just missing his wife. So I hope he moves on and becomes a father."
