It’s been nearly six years since rapstress Missy Elliott released her last album The Cookbook, leaving many of her fans wondering when its follow-up is dropping. Now Elliott has revealed to People that she’s got a more serious issue to deal with: her health.

Elliott, 39, told the magazine that she was diagnosed with Graves’ disease, an incurable disorder that affects the thyroid, in 2008.

“I was [driving and] trying to put my foot on the brake, but my leg was jumping. I couldn’t keep the brake down and almost crashed,” she said of the ill effects the illness had on her in the beginning. “I couldn’t write because my nervous system was so bad—I couldn’t even use a pen.”This apparently isn’t the only revelation we’ll be getting from the artist either. Missy also mentions that she’ll be the focus of the June 29 season premiere of VH1’s Behind the Music, where she’ll reportedly speak on being molested as a child.Read more:Help name Missy Elliott’s new album
