For six days I didn’t get up except to make a cup of tea, or fry an egg, or lie in the skinny bath gazing at a cracked ceiling. The days punished me with their slowness, piling up the hours on me, spreading their joylessness about the room. A doctor would have said I was suffering from depression. Everything I have read since suggests this was the case. But when you are in the grip of something like that it doesn’t usefully announce itself. No. what happens is you sit in a dark, dark cave, and you wait. If you are lucky there is a pinprick of light, and if you are especially lucky that pinprick will grow larger and larger, until one day the cave appears to slip behind, and just like that you find yourself in daylight and free. This is how it happened for me.
