Troubled actress Daniella Westbrook broke down in tears on live TV on Thursday (21Aug14) as she told of the devastating effects of her cocaine relapse. The British star revealed on Sunday (17Aug14) that she had stumbled in her battle with drugs and was taking cocaine again after 12 years of sobriety. She gave a live interview from Los Angeles, where she is receiving rehab treatment, on Thursday but the chat was halted twice as she descended into sobs. Westbrook revealed her mother has not spoken to her since she confessed her relapse to her earlier this month (Aug14) and she wept as she told viewers about the effect of the news on her younger brother, wailing, "I know I have broken his heart." The former EastEnders star blames her relapse on the collapse of her marriage earlier this year (14) and admits she has snorted cocaine several times since April (14). She told U.K. TV show This Morning, "I'm not where I was with drugs but it's a case of how long would it have been before I was back where I was? And that was what I was really frightened about... "To be honest, when that story was going to be broken, the first thing I said to the journalist was, 'Thank you very much, because you have done me a huge favour'. It's exactly the intervention that I needed. I was frightened to come out and tell people I was taking drugs recreationally again... "I have had a terrible time the last year, which is no excuse to relapse, I know. But at the same time I just felt so broken this last year and I feel like a lot of the times I have been on the verge of having a breakdown... I took drugs and relapsed and I am ashamed of that."
