"It's been awhile since you have heard from me, but I wanted to wish everyone a happy new year and to thank you for your love and support," she wrote. "Last year was definitely a year of self-reflection, challenges and growth. It's always those challenges which show you who you are and what you are capable of overcoming. Trust me, it's not easy, but I am proud of the person I am becoming and look forward to the year ahead. Love you all."
