People who have never been around (or dealt with) acute depression are talking out of their azz.

It is crippling, and debilitating. There is no "pulling yourself up by the boot straps" or "sucking it up".

It is a deep despair and hopelessness and helplessness that cannot be explained.

Anyone who has not had it, that passes judgement on someone who has experienced depression is the lowest scum.

The DIPCHIT ADD, after a morning of drinking:

You despair, repeatedly, constantly! daily basis?
A despair ninny.
Sack up, despire ninny.
