After a whirlwind 2016, Kendall Jenner is looking back on the major milestones that marked her year.

The 21-year-old model took to her app to share with fans the "peaks and pits" of the past year that made headlines.

While revealing that the highlights included turning 21, buying her own home, traveling the world, and continuing to dominate the modeling world, the Keeping Up With the Kardashians star disclosed that struggles with anxiety also played a big role in the last year.

"Anxiety was a huge hurdle for me to deal with this past year (and security concerns didn't help), but I think I'm finally learning how to cope," Kendall wrote.

The star previously admitted on the family's show that she suffers from anxiety, and after a year that saw sister Kim Kardashian robbed at gunpoint in Paris, Kendall's security concerns are more than valid.

Kim — who has only recently opened up and rejoined social media after the October attack — had reportedly been without security in the French city, where she and Kendall were enjoying Paris Fashion Week.

But with Kim's return to the public eye, and a new year underway, the star sounds ready for a brand new start.
