“There’s obviously times when I’ve had to be with my kids all day long, sick and feeling horrible, with no help,” the mother of two continued. “But today, I have help and I should be resting and the guilt is crazy.”
“My head is spinning, and I feel like I should be doing a million things and being with my kids every minute when really I’m very contagious,” she added. “It’s just the hard part of being a parent. It sucks.”

Despite playing Lizzie for multiple years, Duff recently told PEOPLE that she wasnervous about revisiting the beloved characterand getting back into her headspace.
“I’m not gonna lie: I’m a little intimidated,” she admitted. “I’m like, ‘Where is she in there?’ She is in there; she is me. When I was 13, it was such a big part of me … I just have to tap into that and be very authentic to that.”
“Our lives are very different — she’s not a mother, I am already a mother — but I think that’s what’s exciting, to step into someone else’s world whose a little bit different than your own, but I can’t wait,” Duff explained.
“I can’t wait for her adventures, for her heartbreak, to see her goals and what she’s done,” she added.
