With all the success Selena Gomez amassed in 2016, she also dealt with some of the most difficult challenges of her life so far.

Hot off the release of her 2015 record Revival, Selena kicked off the year strong with big hit singles like "Hands to Myself," which peaked at No. 7 on the Billboard Hot 100 chart. She also reveled in time with her BFF Taylor Swift as well as made a point to keep in touch with her adoring fans.

However, as she jetted around the globe for her Revival Tour, she was struck with anxiety and depression due to lupus. She eventually had to cancel the rest of her tour dates and seek out treatment, taking a hiatus from social media as well. But she didn't stay away from the spotlight for too long, as she made her grand return at the 2016 American Music Awards where she delivered one of the most inspiring speeches of the year.

The 24-year-old actress and singer undoubtedly went through a lot in 2016, but it's obvious that she came out of everything stronger. Click through our gallery above to take a look back at Selena's extraordinary year!
