Nobody cares about your stupid anecdotes, because you obviously aren't depressed. nobody chooses to be depressed; If you have a choice than you aren't really depressed. Why don't you also go around telling people with alzheimers to stop being so forgetful? "gee, i could be careless and forget all this stuff or i can just try hard to remember it and then i remember! teeheehee"
what about people who feel like absolute shit no matter what they do? what good does "moving on" do for these people? It's a total slap in the face to anyone who's ever suffered from a mood disorder when you dismiss their condition as weakness, simply because you don't understand it and don't care to either.
