Upsides of being down — the positive side of depression.
Having spent most of 2006 and 2007 going through this myself, I can, I think, agree. It was unutterably awful, the worst experience of my life bar none (happily, both my parents are still alive) and I would not choose to repeat it but on the other hand, on the other hand, I am, somehow, improved, I think. I don’t know if I’d go so far as to say more resilient but yeah, with a better perspective, less rose tints (but also no yawning chasms of nihilism), and a bit more serious. But don’t worry: not too much more.
To explain why depression has not been “bred out” through Darwinian natural selection, theories have suggested that rather than being a defect, depression could be a defence against the chronic stress that misguided people can put themselves under. It is possible that depression defends us against the tendency to deny our true needs by chasing unobtainable goals and helps to bring these needs into sharper focus. More specifically, the proposed benefits are as follows: removal from a stressful situation, introspection, problem solving, the development of a new perspective, and reintegrating this with the community upon recovery.
On a related but geeky note, it’s very annoying that the otherwise excellent Guardian Unlimited fails (yes, epic) when it comes to search. Go to the front page and search for “upsides of being down”, the title of this article. It’s a hit but you have scroll down a long way to see it; google, on the other hand have it right at the top, on the day it was published — damn, they good! So come on, Simon, sort it out. ;-)
