Bruce Willis' wife Emma Heming Willis is facing challenges amid the actor's health battle.

Emma took to Instagram to reflect on the hardships she has faced since she and the rest of Bruce's family announced his diagnosis of frontotemporal dementia, which can cause communication difficulties, in February at age 67.

"I think its so important for us to break up our thinking which can feel, for me very much, like gloom and doom," the 47-year-old told her followers as she sat in her car post-hike. "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 I can."

As for what motivates Emma? Her family, including her and the Die Hard actor's two daughters Mabel, 11, and Evelyn, 9. 

"I do that for myself—I do that for our two children and Bruce," she continued, "who would not want me to live any other way. So I don't want it to be misconstrued that I am good because I am not. I am not good."

But that doesn't mean it is a small feat, as Emma noted it "doesn't come easy" to her.

"I am just doing the best that I can always. Your pictures are making me happy," she continued. "I just want you to take a moment out of your day to break it up for a minute to just look for something beautiful."

Getting emotional, Emma concluded her message, "I have to put my best foot forward for myself and the sake of my family. Again, when we are not looking after ourselves we cannot look after anyone that we love. So, it is really important and, like I said, this is a conscious effort."

"This is a care partner PSA," she captioned the heartfelt post Aug. 14. "My message is simple. When we are not looking after ourselves, we are no good to the people we love who we want to show up for and take care of. I don't have this down to a fine science either, but I try. It's an affirmation I use daily, so it's kept in the forefront of my mind. Your pictures, words of support and love for me and my family were felt. Honestly, thank you, it helps."

Back in May, Emma shared how she has found a new purpose in learning and educating about brain health since Bruce's diagnosis. She—along with Bruce's ex-wife Demi Moore and their three daughters: Rumer, 34, Scout, 32, and Tallulah, 29—have leaned on one another, but she has also found a support system in others.

"What I really was yearning for was community, to be talk to people that are on this journey, that understand this journey, because I felt a little isolated for a while," she explained. "So I think being able to use my platform and raise awareness around dementia and be able to have this conversation with caregivers has been really important to me. And I want to take away that stigma, because there is nothing shameful about what is happening."
