Churchill was a national hero who led the British people to achieve great victory in the anti-fascist war during World War II. He was one of the "Big Three" alongside Stalin and Roosevelt. He was a great man who stood in the annals of world history.

He called his depression a "black dog" and told the public based on personal experience: "If the 'black dog' starts to bite you, don't ignore it. If the serious symptoms have lasted for several week, and if you still have suicidal thoughts, you should see a doctor as soon as possible." Churchill, who was open-minded and had a wide range of interests, did not lose to depression. He told everyone that despair can be defeated.
