There are a multitude of factors that add to this, but it is slightly insufficient to say that it is fully becoming more of a problem now. Certainly it is more, but there is a little hype over it - it is understood more in modern times, the study of psychology is more open, in older times it was a little taboo, etc. Beyond that, the chemical compounds in food, the parental upbringing of children being either badly done or resulting in premature grown-ups, the television being both a negative source of enjoyment and a controlling societal factor, etc. are also all factors.
I like to think that the suffering is worth it. Perhaps I think this way to somehow give value to that which I hate, but it at least gives me some wisdom. In general though, to others in the world and partially myself as well, people are not able to handle being sad and act often like it's exclusive to them. It's like a bomb of the tragedy of commons; saying I am sadder than everyone else, with many individuals saying it, leaves the world sad and the people saying the aforementioned phrase ignorant.
As for its remedy, all that I think is required is a hug.
