Solange Knowles is getting personal.
The 31-year-old singer opened up to fans on Wednesday, revealing in a lengthy Instagram post that she was diagnosed with Autonomic Disorder and is forced to cancel her upcoming New Year's Eve concert in South Africa.
"Wrote, deleted and re-wrote this like 5 times," Solange began. "Still not sure what exactly or how much I want to share. However it’s so important to me for the people in South Africa, a place that has tremendous meaning to me and that has given me SO SO MUCH, to know why I won’t be performing at Afro Punk this NYE."
"The past five months I have been quietly treating, and working through an Autonomic Disorder. It'[s] been a journey that hasn’t been easy on me... Sometimes I feel cool, and other times not so cool at all," she continued.
While the "Cranes in the Sky" crooner didn’t go into detail about her disorder, Solange stated that it has been a "complicated diagnosis."
An Autonomic Nerve Disorder affects the body's autonomic nervous system, which controls much of the body's involuntary functions and can include problems with heart rate, blood pressure and body temperature among others, according to the Mayo Clinic.
"I’m still learning so much myself, but right now, my doctors are not clearing me for such an extended lengthy flight, and doing a rigorous show right after," she explained. "I can’t put into words how saddened and sorry I am that I am unable to perform for you guys this NYE, there is simply no other place I wanted to be than there with my family to bring in 2018 with you.......but I give you my ABSOLUTE WORD I will come back with AfroPunk and deliver this performance.....as it is so extremely important to me to connect with the people who have so closely inspired me in so many ways."
The singer continued by thanking everyone who knew about her health issues and kept it under wraps.
"As a part of the self-care that I’ve tried to encourage this past year, it needs to start with myself, and I’m looking forward to doing a better job of this 2018. This past year has been one of the most fulfilling of my life," she expressed, adding that she's appreciative and excited about what's to come.
