Dreijer and her band were set to play seven more European shows in October and November, having spent much of the year touring in the wake of the new album, Plunge. She canceled those shows via a Twitter announcement today, saying "the last month has been rough, and my anxiety has started to escalate."
"For seven years I did not enter the stage," she explained. "For five years I did not enter an airplane. It is a disorder that always lurks in the shadows that I have had to work carefully with and around, and that I never really know when it will strike or how much it will affect me."
