Cured is not, unfortunately, a word in the PTSD lexicon. But that glimpse of a world without sickness – it must have lasted two, maybe three hours – was enough to make me long for more, to give me the energy to reach for more. The next intimation of normality would last longer. Eventually, one lasted a whole day. Gradually the world of colour and beauty began to reform itself around me, like a jigsaw.
