I've heard arguments similar to yours many times. I've tried mid-20th century French philosophy, and do appreciate it. But it doesn't help.
Depression manifests itself differently in different people. There isn't a "correct" form of depression. Telling people that "you're not depressed, you're X, do Y and all will be OK" doesn't help at all.
You probably mean well, but making those sort of comments do everything but what you think they do.
