It's a good day to quote Heiner Müller:
"Yesterday I stopped killing myself. I am alone with my breasts my thighs my lap. I rip apart the instruments of my imprisonment the Stool the Table the Bed. I destroy the battlefield that was my Home. I tear the doors off their hinges to let the wind and the cry of the World inside. I smash the Window. With my bleeding hands I tear the photographs of the men who I loved and who used me on the Bed on the Table on the Chair on the Floor. I set fire to my prison. I throw my clothes into the fire. I dig the clock which was my heart out of my breast. I go onto the street, clothed in my blood."
Yesterday I stopped killing myself. Not much more is needed. You can live on a minimal diet.
