Marsha Linehan created DBT, a comprehensive mindfulness and cognitive therapy to work with suicidal, especially Borderline Personality disordered clients. She recently revealed, in a NYTimes article, that she was an out-of-control self-destructive Borderline client as a teenager here: http://www.nytimes.com/2011/06/23/health/23lives.html?_r=2&src=tptw
I like DBT. With the addition of ego state therapy and a trauma remover like EMDR, it works very well. I especially like its emphasis on mindfulness to help with affect regulation and good therapeutic containment.
