To the Editor:

Donald Trump has been great for my small business. I’m a psychiatrist, and my practice has been full since he was elected. Depression and anxiety plague my patients because of the powerlessness they feel about the destruction of the America they hold dear.

The ones whose symptoms have remitted have one thing in common: doing something concrete to oppose him. Taking personal responsibility by taking actions, large and small, has led to a universal sense of relief.

Anyone can do that; just vote.
