I started getting these attacks in 2009, just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist, who told me I needed to make peace with my panic attacks.

I want to be safe in the knowledge that I can tour and play festivals for a long time. The main thing is that I want a good reputation as a live performer. If I have that, I'd be so happy.

I maintain that when I finally retire from my career in music, I will go and live back in Wales - when I am an old person, if I live to be an old person. The water I miss, and the air, there's something different about it. And I miss the simple life.

Well, on tour I eat terribly, so I balance that by running a lot. And then I started to run with my fans in certain cities. It sounds very nerdy and un-rock n' roll, but I like it. It's fun, and it's better than meeting fans in weird, awkward circumstances. So I take them running with me.

I never expected to get the Tom Jones treatment and it amazes me that I do. Strangely it's women who throw their underwear at me when I'm performing live. My male fans tend to be quite shy. My female fans are wild. I never know what to do with all the lingerie that lands at my feet. Maybe I should open a shop.

I could always sing, from a really young age, but my voice was really weird. I used to make my mum turn up the radio every day in our house. She was well into music so I got that from her.

Apparently I'm introspective... levelheaded... but at the same time, absolutely insane.
