The implication that depressed people are fundamentally irresponsible is a deeply damaging and counterproductive one. Winston Churchill was a depressive. He didn't just fly planes; he was in charge of the Royal Air Force.
And then he - Tchaikovsky - turned towards the little lectern that was on the stage, picked up his baton and held it in the air. He paused a moment. It was like watching an old wizard with a wand, summoning the energy needed to cast a spell... Time slowed inside that moment. Then the music began.
What doesn't kill you very often makes you weaker. What doesn't kill you can leave you limping for the rest of your days. What doesn't kill you can make you scared to leave your house, or even your bedroom, and have you trembling, or mumbling incoherently, or leaning with your head on a window pane, wishing you could return to the time before the thing that didn't kill you.
The weirdest thing about a mind is that you can have the most intense things going on in there, but no one else can see them.
Look at the sky; remind yourself of the cosmos. Seek vastness at every opportunity in order to see the smallness of yourself.
Beauty breeds beauty; truth triggers truth. The cure for writer's block is therefore to read.
