It was impossible to sleep. Anxiety stopped me from falling asleep; depression woke me up.

I haven't put much effort into my personal life and blithely believe it will turn out all right in the end.

I still enjoy my life, and I feel like I've achieved enough things that if I never did anything again, I'd feel confident that I'd still have made my mark in some way. But maybe the self-loathing bit is the element that makes you strive for more. Makes you strive to be better.

I don't have a fear factor. Well, not much of one. And I'm willing to risk quite a lot - as a comedian, you're always risking a lot. You're risking failure, especially if you're improvising and going on TV shows trying to make comedy out of thin air. That is quite a risky business.

I've done panel shows, which I enjoy, and on those you're recording half-an-hour of TV and sometimes they film for two hours. But with 'Britain's Got Talent,' you're on camera for eight hours, with a large theatre audience watching - and in between you're being filmed for ITV2 as you eat your lunch.

I would recommend that anyone who wants to do comedy on TV to do radio first.

In Britain, a cup of tea is the answer to every problem. Fallen off your bicycle? Nice cup of tea. Your house has been destroyed by a meteorite? Nice cup of tea and a biscuit. Your entire family has been eaten by a Tyrannosaurus Rex that has travelled through a space/time portal? Nice cup of tea and a piece of cake. Possibly a savoury option would be welcome here too, for example a Scotch egg or a sausage roll.
