It is true that things can be worse, but it does sound like a way of dismissing somebody's feelings, and that's one of the worst things somebody can do. Most depressed people, including myself, realize that there are people worse off than themselves, so telling them that things can be worse does not help at all. Right now I have a hurt foot, but am I supposed to feel better knowing that somebody out there has broken their leg? No, I am not, otherwise not only would I come across as immature, but a sadist.
