It’s been just shy of three months since the passing of Carrie Fisher and her mother, Debbie Reynolds, and the world is still mourning. It’s hard to imagine what the grieving process has been like for Billie Lourd, losing her mother and grandmother within a day of one another.

Carrie’s brother Todd Fisher told Entertainment Tonight that Billie just needs some space to heal. He said:

“She’s dealing with two gigantic losses. These two girls — my girls, my mother and my sister, were big, big personalities [with a] big influence on Billie, myself, many people. … There’s a vacuum in the room and she’s feeling it and we’re all feeling it. It’s just that I’m 59 and I have no choice but to step up and put this stuff forward. I’m letting [Billie] breathe, you know? She needs to breathe. She needs to step back from all of this loss.”

Todd also shared that seeing Billie going through such pain was worse than his own. He said:

“When I was standing in the room the day after my sister died and we’re in the hospital and my mother was dying, I mean, I was more heartbroken watching my niece than I was for myself. It was heart wrenching. The idea that somebody would have to deal with that kind of a loss back to back, moment to moment — I mean we’d just had this horrible loss and then here you are just a handful of hours later standing in a different hospital in a different room. It was astounding.”

Billie’s uncle has great faith in his super strong niece, though, and her ability to persevere. He told ET:

“She’s also genetically Carrie and Debbie.” He added, ” [But] You take those genes, and I think you’ve created a pretty powerful gal … She is a lot more like my mother even than Carrie. You know, she’s a little like Carrie but she’s a lot like my mother, which means she’s going to be another Molly Brown.”

We send continued love and strength to Billie and her loved ones.
