Kendall Jenner has endured a "tough two months" battling mental health issues admitting she's been feeling "more sad than usual".

The 28-year-old model and reality TV star has been opened about her anxiety issues over the years and she's been going through a particularly rough patch confessing she hasn't "been myself".

She told Vogue magazine: "I don’t see why I shouldn’t be honest about it. In my career right now I feel really stable, really hopeful. But I’ve had a tough two months. I haven’t been myself, and my friends see it. I’m more sad than usual. I’m way more anxious than usual.

"So I’m not going to sit here and act like everything’s perfect. That’s life - I’m always going to be in and out of those feelings. In past interviews, when someone’s asked me about my mental state, it’s always been, ‘I’m great right now, but this is what I’ve dealt with.’ Well, right now I’m actually in it."

When asked what's been causing her distress, Kendall admitted she might be going into her Saturn return - an astrological rite of passage which happens every 29.5 years and is said to signal big life changes.

Kendall added: "Let’s just say it’s personal-life-journey stuff. I’m a stresser and a control freak by nature. I’ll thank my mom for that one. This is also kind of a transitional period for me. I’m 28 now, and I think I’m in my Saturn return."

However, Kendall is hoping she will get her emotional issues out of the way now before she turns 30 next year, She added: "I’m so tired emotionally, but I think it’s good. It’s almost like I’m purging something for my 30s. That’s my theory."

Kendall has suffered panic attacks in the past, but she has adopted coping methods including deep breathing,, meditation, journaling and weekly psychotherapy and she has not had another episode in two years.

She went on to add that she needs to continue being active to help her mental health and she always knows when she's setting herself up for "failure" by not using her coping strategies.

Kendall added: "Getting out of bed in the morning and putting one foot in front of the other is so helpful for me. Moving, getting my blood flowing. When I say I’m struggling right now, I’m not doing those helpful things.

"Choosing to sit in my bed and mope all day is setting myself up for failure.”
