I am with Reine on this I think... why should there be a 'cure'...to what exactly? This assumes that there is something wrong that needs curing. For me the 'cure' will come when I am truly happy in myself. Not sure that I will ever get there as that is in my nature... I question too much so will never have the definitive answer, nor the cure...
In all aspects of life there are no right answers... but there are wrong answers... but then we need to understand the questions - both of others and the ones we ask ourselves.
Quitting? Yeah it is a choice. For many it doesn't work, but for those it does work for, of course we never hear from them again. What we need is an ex-CD to come back here and say... it has been 10 years and I don't miss it! But they won't... because they don't need to.
And so to the scientists and engineers... My first degree and job was in science - microbiology... I like to think that I have never lost that approach, even though I now work in social sciences (very different but with similar problems regarding evidence and causality (or 'proof'))...
So evidence is always good in a constructive argument, and if we can't provide that, a well reasoned narrative is a pretty good alternative!
And to those of us who believe we can't put a sentence together (yeah I am there at times! )
