Maybe they use the words "I, me, and myself" more often because they're trying to explain why they're sad to everyone who is trying to force them to be happy.<p>Seriously.. my wife and I have lost seven children before birth at this point, late enough in pregnancy to make them actual medical events, and to say we're sad and stressed is an understatement. The amount of people who have told us to forget about it and be happy is off the charts ridiculous. Hell, someone suggested we go on vacation, while my wife was hemmorhaging in the hospital, as if that would make it better. Obviously, we use the phrase 'I feel' or 'We feel' a lot -- saying "You're being obnoxious and a shithead" is a lot less socially acceptable than saying "I don't think we can do that right now".<p>I have a friend whose mom died while he was fairly young, and he used the phrase 'I feel' a lot too to explain why he was sad a lot of the time.<p>It's not surprising... happy people have little need to convey how they feel -- it's usually quite obvious, and everyone loves being around them. Sadness on the other hand, everyone wants to avoid, and most people are shit poor at being able to figure out when someone is down in the dumps.
