I entered the museum thinking that Van Gogh was a lonely, depressed genius for whom art 'just happened'. I didn't know that he had a loving brother who he wrote to often and who supported and encouraged him throughout his career. He was a genius, but he worked very hard for that genius, taking many art classes and studying the work of many other artists.
Van Gogh was depressed and did suffer from severe anxiety. But. Even in his darkest times he continued to paint, to create and to hope.
