I still love coming into work everyday after so many years working as an actress. I've been working more or less continuously and I find I have to really want to do the project to make it work because you have to put such an enormous amount of effort into it.

I'm becoming more squeamish. I didn't use to be - nine years of 'Silent Witness' prepared me for most things one will have the misfortune to see in life. Before, I'd be wading up to my neck in gore, but now I tend to look away.

But I didn't really enjoy my secondary education that much, probably because I am a very physical person and don't enjoy sitting at a desk all day. I just dragged myself through GCSE and A Levels, so it suited me very much to go on to drama school, which was very active.

I was on holiday recently and I came home to find that one of the papers here had 'bikini'd' me on the beach. I was wearing a grossly unflattering costume and they had published photographs of me taken from behind. I looked dreadful. I went into our local newsagent and bought up every copy.

I always start from scratch with a character - they're never based on anyone else. You get ideas of what people look like, and I'm a great people watcher. You can draw inspiration from people.

I think some people think that being on television makes you a sitting duck, but you have the right to remain private.

I have sleepless nights before press days.
