Imagine that practice married with a political agenda that decides millions of are "depressed".?.
It's not always a temporary problem. Mine is chronic for about 40 years now and gotten much worse over the last 15 years. My life still has meaning to me, you learn how to live with it, you aren't fully functional like most people you know, but it is still worth living, and you can still accomplish a lot, contribute a little to society, and be there for your family.
This idea is ridiculous and dangerous especially because for a lot of people, depression is more or less temporary and can be treated in numerous ways. To end your life because of it, I understand why some people do that, but the worst eventually passes if you tough it out. Every day is not bad, and some people only have one major episode in their entire lifetime and bounce back and have great, normal lives for years and die a natural death in old age from something else.
