I think the secret of memoirs is keeping those parts of yourself off the page, which makes what you do share more valuable.

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.

You don't realise how much you're holding onto until you start to let go of it. I had had loads of therapy and thought I had come to terms with who I am, but there's something in the process of writing that unlocks other experiences, other emotions and you have to be prepared for that.

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.

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.

The hardest bits of my book to read were the easiest bits to write because they were the most immediate. Probably because I had never stopped thinking about them on some level. Those bits I was just channelling and those were the most exciting writing days. The bits I found harder were the bits that happen in between, you know, the rest of living. There were whole years, whole houses, that I just got rid of.
