Where on earth did you get this gem from?  Depression results in people not
getting enjoyment out of life, not feeling motivated to do things they
normally would, sleeping differently to normal (more or less) and thinking
of suicide.  At no point in DSM does it say that depressed people are more
likely to write a symphony!

What has this got to do with helplessness?  When a rat is given
uncontrollable electric shocks, it cannot subsequently learn to make an
action which will reduce the probability of a shock.  In what way is this
adaptive?  Strangely enough, theres more seasonal effective disorder when
there is less sunlight in the winter months - hence Northern European (don't
know the stats for Canada - I presume they have the same problem?)
