Not throwing the blade at all, Pedro. And if any blade hit home and hurt, I apologise. I meant what I said, in that I usually manage to keep the black dog of depression at bay with music. Literature I tend to avoid, as most of my favourite works tend towards the maudlin, and don't help life the spirits, and comedy writing barely appeals when I'm feeling good, and comes across as particularly leaden when I'm feeling down.
And I'm afraid I have foudn myself singing Dick's song when I'm down - the Victorian bathos of it, coupled with the schoolboyish scatology, do make me smile.
But, as many have said in this thread, there's no panacea for depression, and one person's particular remedy can clearly be offensive to another.
Personally I would avoid any chemical aids, both proscribed and prescribed. My own experience is that they all tilt the brain's chemistry to such an extent that, although the immediate, almost physical effects of the depression are relieved, other problems kick in - things like a change of personality, a loss of motivation and a feeling of a lead weight pressing down on the consciousness.
To repeat - there is no universal cure, but laughter, song and good companionship come closest.
And apologies again if any feelings were hurt. I know depression makes minor hurts seem like greater blows, and perhaps I should have registered that before posting, But I too was being very serious. If you love a good joke, go out and collect and share as many as possible. The best jokes are a different take on the human condition and can be very cathartic.
