He is a good doctor. He tells me all about SSRIs, talks me through their side-effects, their history, their mode of operation. He draws little diagrams of neurons, adds dots and wavy lines for serotonin molecules and the action of re-uptake inhibitors. I peer at the pictures, fascinated. An hour later I’m walking down the street with a white paper bag in my hand. It weighs almost nothing. He says it will make things better. Which is ridiculous. How can this grey and mortified world be washed away by little dots and lines?
