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.

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.

I started writing when I was a journalist. But every time I sat down to write a novel or a story, I ended up writing about myself, which was incredibly annoying and self-involved.

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

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 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.
