"But there's obviously a certain skill set that's needed in being a full-time mum, and I guess I get to have a test run.
"But, like everyone else, I go sit in my parked car outside of my house, lock the doors and sometimes just cry off my fake eyelashes."
She admitted her anxiety also comes from fears she won't be a good mum.
"I've always wanted to be [a mum]. I didn't know if I could be that, or if I'd have the capacity.
"My sister is the most maternal one in my family and I'm a logistics strategiser, you know, show off, and I didn't have the maternal gene, so I've had to really learn how to have that."
She wrote to her Twitter followers that she's struggled with the impact of the pandemic.
"Sometimes I don't know what's worse, trying to avoid the virus or the waves of depression that come with this new norm," she tweeted.
But quarantine has given her the chance to get some parenting practice, as she's currently isolating with her nieces and Bloom's son Flynn.
"It's been wild, I'm quarantining with my 3-year-old and 6-year-old niece and then Orlando's son who's 9 and, you know, just getting used to having kids around the house."
