I agree with you until you say that "depressed" is normal. Really, it isn't, it is abnormal. It is also treatable. People who eat better, get exercise, and regulate their use of stimulants / sedatives tend to do well. Adding in a course of cognitive behaviour therapy (from an experienced practitioner) effectively cures many people. Adding medications helps lots of people too.
Perhaps you're saying that modern life pushes people away from healthy eating and exercise and sensible worklife balance and towards alcohol and caffeine, and that depression is the natural result of that. In which case, I agree.
You mention information overload. Here's a nice example of sub-optimal advice about procrastination. It's too long for anyone prone to procrastination to actually read.
