"I am gay on the outside, especially among my own folk (I count Poles my own); but inside something gnaws at me; some presentiment, anxiety, dreams - or sleeplessness - melancholy, indifference - desire for life, and the next instant, desire for death; some kind of sweet peace, some kind of numbness, absent-mindedness."
