Award-winning British actress Rebecca Front signed up for special therapy to combat her claustrophobia after she became too scared to fly or travel on the London Underground.

The Nighty Night star has spent years battling a fear of confined spaces, among other phobias, but she decided to tackle the problem with the help of a counsellor after it began to seriously affect her life.

She underwent cognitive psychotherapy and is now able to travel on planes on her own, but she still can't use elevators or ride on underground subway systems.

Front, who won a British Academy of Film and Television Arts (BAFTA) award for best female in a comedy for her performance in hit political show The Thick of It in 2010, tells Britain's The Times, "It hasn't worked 100 per cent. I still don't use the Tube, I still can't use lifts (elevators). But I've been able to go on planes on my own. I used to have my husband with me. It's such a pain...

"You get anxious about everything, get very negative about the outcome of things, then restrict it to: 'I'll be fine as long as I don't do this...' I can go on stage, do a speech... But at the back of my mind I am thinking, 'Yeah, but if I have to get in a lift at the end I can't do it.'"
