Kendall Jenner opens up about her anxiety bouts and panic attacks

"Two or three years ago I genuinely started having very, very bad panic attacks. I was having frights in the middle of my sleep, literally felt heart palpitations. I couldn't breathe. I was pretty bad," Kendall shared ahead of her four-part series with Vogue called "Open Minded", reports femalefirst.co.uk. 

She earlier shared that she has "struggled a bit" with her mental health. 

Kendall said: "I was really, really young and I remember not being able to -- feeling like I couldn't breathe and venting to my mom and being like, ‘Mom, I feel like I can't breathe. Something must be wrong'." 

She added: "She took me to a bunch of doctors just to make sure that I was okay physically, and I was. No one ever told me that I had anxiety. Maybe three or four years ago it came back completely full-on. I would have crazy panic attacks. I finally kind of got the information that I needed about it." 

Once Kendall knew what she was struggling with, she found new ways to cope.
