Thanks Mari - very interesting.

My family history of clinical depression (I don't know about Bipolar) suggests that family things can be important though sorting out the relative importance of genetics and environment would not be easy.

Both my brother and sister have been moderately depressed. I nudged them both into seeing clinical psychologists, which worked with no need for meds. It is good to be able to talk with them - they accept that I need meds as well as using talk-therapy approaches.

Looking back with the wondrous power of hindsight, I suspect that my father was also quite severely depressed.
