Model Gigi Hadid has reflected on her breakout year 2015. She says she will never forget it.

From calling off her long term relationship with singer Cody Simpson, to helping her mother Yolanda Foster battle Lyme disease, she's had a good year.

The 20-year-old took to Instagram to share some of her magazine covers and open up about how the year gone by has totally changed her life, reports eonline.com.

"Thinking back on my most favourite moments of this year brings me close to tears -- both my career and personal journeys throughout seem so surreal in how each change, turn, and decision guided me to where I stand now," Hadid said.

"My gratitude for all the opportunity I was blessed with this year makes me also grateful for any negative experiences, for what they taught me and for where they lead me," she added.

Hadid also credited her team and people in the industry for her success.

"I would not be where I am without my irreplaceable team or without the people in the industry who not only believe in me, but show up to work, inspiring me every day with their talent, energy, spirit, passion, heart, and drive," she said.

But her career aside, she also noted that her fans are one of her biggest driving forces.

She also wanted her fans to know she's not slowing down in 2016.

"#giforce, you helped make 2015 a year I will never forget... I have so much coming for you in 2016. Cheers to you."
