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.

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 do feel a responsibility. It's a privilege to be able to speak about it, but I don't speak for all gay people.

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.

If you are a Scot living outside of Scotland but still in the UK, you are not allowed to vote in the referendum. This leaves over a million of loyal, proud Scots disenfranchised. It gives me the rage.

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.
