Without much to go on, let me remind you that many, most - perhaps even all -artists suffer with some mental illness, or another. Michelangelo Merisi da Caravaggio, Vincent van Gogh, Jackson Pollock ... and a slew of Legendary Giants, all down the line, have had their maladies of the mind that some might even call "excentricities."
But the one thing they all had in common was the brilliance of their work. As artists, we mustn't compare ourselves to other people, for it is we who are the avant-garde of every aesthetic. Its passion demands expression - not censorship. Its creativity thrives in freedom - not captivity. The Creative Path should never be questioned, but rather, simply followed.
Now, if money is no object, regarding these courses. Maybe your family is paying, or you have government money to burn, then absolutely, pursue your passion at this school! Burn your subject matter with your glance ... and make ... ART!!!
