What on earth must I have been thinking, and how on earth did I end up doing such a thing? The stress gets too much: the emotional will eventually manifest itself in the physical, and when that happens, you're totally fucked, because a feedback loop is created.

A feeling of grogginess is the only comfort. Let the muscles relax and let that brain untangle. And when that happens, the creativity can flow once more. All the other shit is revealed as mere stupidity.
