I doubt it really does bug that many people. Being clinically depressed, it's pretty much a constant in my life and even I joke about how I ate some crappy meal that made me depressed, or whatever offhand 'oh-so-depressed' joke fits.

I find its the people who are not depressed who feel sensitive about the word, while depressed people are 'used' to their condition and usually understand the difference between 'iwanttodie' and "I'm so depressed cuz my favorite thing ended".

Just my experience or anecdote, not fact
