Sandra Bullock's wake-up call that changed everything during late partner Bryan Randall’s illness

A sobering warning from Sandra Bullock’s sister became a wake-up call for the actress as she quietly navigated her late partner Bryan Randall’s battle with amyotrophic lateral sclerosis (ALS).

Bullock reflected on how caring for Randall through his illness forced her to recognize her own limits – and ultimately ask for help after years of putting others first.

"I'm always a caretaker," she said during an appearance on "Good Hang with Amy Poehler." "Always.

And I learned that I didn't take care of the person that was taking care of everybody else.

And that was a big wake-up call for me.

And I'm not good at asking for help, but I needed help and I needed to ask it in a way that was safe."

She also credited her sister with ringing a much-needed alarm, warning that she needed to start taking care of herself so she could continue being there for her children, Louis and Laila.

Bullock said her sister warned her: "If you do not start taking care of you, something’s gonna happen to you." Bullock said the experience opened her eyes to the toll caregiving can take on those who put their own needs aside.

"I did what I had to do in the situation I was in." "I didn't want to say anything out of turn on what anyone else experienced within that situation, because everyone is experiencing something, their own journey with that," she explained.

"There's so much to the story that would be of service.

But my story, my slice of pie – and me and the kids, you know – that's all we can speak about." Bullock revealed her minimal history as a caregiver during a recent episode of the "SmartLess" podcast.
