First off
Apologies to anyone I may have angered, it was not my intention.

No, unfortunatley, I am not unfamiliar with mental illness. Being at the functional end of the autistic spectrum myself and also subject to bouts of depression make my head not a happy place to live in. Self medication is not the answer, while cannabis and alcohol can, in large quantities, alleviate some of the pain they have a definate, and obvious, functional cost. It also forms a vicious circle.

But back to the original discussion...
Is depression part of the hibernation system ?,
to retreat and withdraw during adverse conditions ?
Is depression part of the hibernation system kicking in at inappropriate times ?
