Along with using music as an outlet, she explained she's able to cope with certain experiences and topics through therapy and humor. "Although that's uncomfortable and painful, it gives you something to work with," she said of seeing a therapist. "I think the reason I can go to such uncomfortable places and be so honest is because I have a really healthy sense of humor."
The 39-year-old star has two kids with her husband Carey Hart, Willow, 7, and Jameson, 2. The famous couple has been together since 2001.

Just last week, she told Ellen DeGeneres how she's "prouder" of having her kids out of anything she's ever done. However, she revealed that she wouldn't be sharing them on social media anymore.
"I like to share my family. It's my proudest moment in my whole life. I'm prouder of my kids than anything I've ever done," she said with some emotion in her voice. "I won't share them anymore. I won't do it. I'm not posting pictures of them anymore."
