This is unfair. It's more like:

1986 - I feel sad. Well that's life. Kills self six weeks later

In other words, it's not that people today are getting treatment for things that people in the past just knew how to live with; people today are getting treatment for things that people in the past died from. People drank themselves to death, or ODed on drugs, or put a rope around their neck, all because they couldn't calm the storm raging inside their head.
