A good practitioner never talks about their own practice hehe :-)
Fun besides, all I can say is that the practice of mindfulness is rather interesting. At some stage what will happen is that we won't take our own ideas so seriously — i.e. they will not be "so important". "The world will not end" if I don't do this or that, or, vice-versa, the world will also not end if I do this or that. Once we really start to experiencing that, it becomes progressively easier to deal with frustration and even depression, as we notice that all those "depressing thoughts" are not as solid as we thought...
On the other hand, it takes a lot of time and a rather serious commitment in order to achieve results. I was actually surprised with that article you linked to! It's just because some sorts of cognitive-behavioural therapy (clearly inspired in Buddhist practice) take just a few years to have some effect (if the patient is very willing to commit to it), while a more traditional Buddhist mindfulness practice can take much longer — but its effects are permanent!
My own wife, who went through a few episodes of panic attacks, actually combined both techniques, plus some medication at the beginning. After a couple of years, her doctors were actually surprised that she dropped the medication almost completely but still continued to improve. Her own explanation is that a more conventional cognitive-behavioural therapy just achieves a certain degree of eliminating depression, but can achieve that relatively quickly, while Buddhist practice, once taken hold of your mind (pun intended!!), tends to go way beyond what therapy is able to provide. Because it takes longer, however, and because Westerners want results fast, it comes as a surprise to me that it's seriously being considered as an alternative.
One point worth emphasising is that cognitive-behavioural therapy is not 100% successful forever; you might relapse, and require new amounts of medication, start from scratch, etc. The Buddhist practice of mindfulness, once mastered, will never "go back". Put into technical terms, once you realise the nature of your own mind, you cannot be deluded again in thinking it's something different than what you've realised

At that point, depressive thoughts cannot affect you any longer — ever. Now, achieving that result, that's hard stuff :-)
