Suppose Vincent van Gogh was a Dutch post-impressionist painter who is among the most famous and influential figures in the history of Western art. In a letter to his brother Theo, he once wrote, 'I am unable to describe exactly what is the matter with me; now and then there are horrible fits of anxiety, apparently without cause, or otherwise a feeling of emptiness and fatigue in the head... At times I have attacks of melancholy and of atrocious remorse.'
Can we infer that 'Vincent van Gogh never experienced any mental health issues?' Yes, no, or maybe?
