I agree. The stress conveyed on these boards is disheartening. Beginning a PhD program means embarking on the next 6-8 years of your career. I'm amazed that people are pulling all nighters and generally "obsessing" about their applications. I don't think this is healthy. Is this really how you plan to spend the next decade, people? If grad school makes you a crazy person, maybe it's not worth it. There are plenty of great careers which don't take years off of your life.
My question to posters is, how do you justify this stress?
For passion (shouldn't it be healthier), prestige (if we were smart, wouldn't we be smart enough to choose not to do a PhD), or a paycheck (ha! just kidding)?
