Josephine King remembers her first self-portrait and how it showed up out of nowhere. She was "really ill" with bipolar disorder, living alone in a flat in Amsterdam. "I was in psychosis. I was desperate, not at all well in my head. I thought, the only thing to do is a painting." She worked until a woman emerged against a brilliant pink background. This was the painting that launched five years of obsessive self-portraiture, framed with texts spelling out what it is to be manic depressive. An exhibition of 80 self-portraits are on show at London's Riflemaker gallery.
