Well... I've never been officially diagnosed as having bipolar disorder. (Actually I've never been officially diagnosed with anything although I've been kicking around the mental health system where I live for over 20 years.) One psychiatrist I saw in the hospital, following my second S attempt, did say she thought there might be "a bipolar element" to what was going on with me (whatever that means.)
Anyway I think a thread dedicated to S prevention strategies could be most useful. I don't know if I myself would have much to offer because both of my major attempts, along with one other almost but not quite silly one, (it's a long story) were spur-of-the moment decisions. (I've told several mental health professionals I've seen over the years that if I were rational enough to know I was in trouble & call someone then I wasn't in any real danger. But if I was really in trouble the last thing I would be likely to do would be to call someone.) However I would presume other PC members would have useful strategies they might be willing to share. I do more-or-less believe that, at this point, I'm done trying to delete myself from this level of reality, so to speak. Hopefully nature will simply take its course... sooner rather than later. But you never know...
