If you are not familiar with it, Grave of the Fireflies is one of the most depressing movies I have ever seen. It’s set mostly in post war Japan and within the first few minutes of the film you witness the protagonist die and be met by the ghost of his younger sister who dies before him. 😐 Anyway it’s definitely not a film I recommend watching when you are depressed. Also I have to add that it is not a good practice to be taking depressed persons to a very sad film.
