Emma Heming Willis, the wife of actor Bruce Willis, has spoken about the struggles she and her family face as her husband's untreatable dementia progresses.
Action star Bruce Willis received the diagnosis in spring, less than a year after he retired from acting because of growing cognitive difficulties.
Ms Willis, herself an actor and model, married the Look Who's Talking actor in 2009.
She addressed the worry she feels around the perception that she is "out living her best life", while her husband is seriously ill at home.
In a video posted on Instagram on Monday, she said, "I know it looks like I'm out living my best life - I have to make a conscious effort every single day to live the best life that I can."
She continued, "I do that for myself. I do that for our two children. And Bruce, who would not want me to live any other way."
She then begins to cry, before saying, "So I don't want it to be misconstrued, that like I'm good.
"'Cos I'm not. [I'm] not good."
She said she tried to be positive every day for the sake of her family, despite the reality of her husband's diagnosis being very challenging.
"I have to put my best foot forward for the sake of myself and of my family. Because again, when we are not looking after ourselves, we cannot look after anyone that we love.
"So it’s really important, and like I said, this is a conscious effort... I'm just doing the best that I can always."
In recent days, Ms Willis has been asking her followers who are themselves carers for loved ones to share photos of "beautiful moments" of their days, in attempt to bring some positivity to the "doom and gloom" she sometimes feels about her husband's condition.
68-year-old Die Hard star Willis has frontotemporal dementia (FTD), which is an umbrella term for disorders affecting the areas of the brain that deal with personality, behaviour and language.
A statement released by his family in February, which was also signed by his ex-wife Demi Moore, said, "We know in our hearts that - if he could today - he would want to respond by bringing global attention and a connectedness with those who are also dealing with this debilitating disease and how it impacts so many individuals and their families."
