Depression is a very complex problem & for many "normal" people, it can appear as though it only needs a little "positive thought", and the
sufferer can just "pull themselves out of it".
Unfortunately, this isn't the case.
For most sufferers, depression is brought on by a number of factors, not necessarily related, and often not even the kind of
dramatic events (
bereavement,
divorce etc..) that lead to the troughs that everybody goes through in life.
With the aid of
medication & personal counselling from a
psychiatric professional, most sufferers can begin to cope with these factors & find ways to break the cycles that led them downwards. With this help, a great many can "recover", or at least live a comparatively normal life".
Feeling down is a normal occurrence, but depression is an illness & should be treated as one. You wouldn't suggest that diabetes will just disappear if you "think positive", so please don't do the same for depression.
