Because I work at other things, whenever I get a chance to write I feel grateful for it. But I learned that sometimes, I couldn't do anything else and I shouldn't plan to do anything that night or the next day. There were times when I was writing something difficult for days or weeks and when I'd finish, I would get up and go out of my shed into the garden and be sick. I had terrible migraines.

I could never do just one thing, but everything I do is in the direction of stories. Sometimes writing them, sometimes showcasing them, sometimes letting people see them.

I went through in the edits and cut tons of stuff that was "funny" because if it wasn't funny at the time, so it shouldn't be funny now. It's about having that unity of experience. You have to try and take away your hindsight knowledge of a situation.

The stories we tell ourselves about ourselves are very often not really what happened. And as I started to write stuff down, I started to challenge what I thought I knew about myself, my culture, my family, all of it. It was a huge, destroying process that completely took over my life. I just wasn't here, I mean I was physically present, but I wasn't here, I was back in the 1980s.

Memory implies that there is some static time and place you can go back to, whereas if you relive it by trying to put yourself back in that context, its more nuanced, less black and white. More traumatic, but also more exciting. When I knew I had to write about things that would be painful, I put off doing it for ages. But then eventually the fear of not doing it becomes greater than the fear of doing it.

Scotland has always been independent. We have our own legal system, our own culture; I don't see the issue. We are different and I think we should celebrate those differences within the union. I can see what would be lost, but don't necessarily see what would be gained by breaking away. What does upset me is that I can't vote in Scotland.

I had to do things to myself on the page that had been done to me in real life. I had to try and drown myself in the bath. You have to do that. And the impulse is to rescue yourself and to spare the reader, but I can't rescue myself. And why should I spare the reader when nobody spared me? It's telling people what happened.
