All women are crazy, all men are jerks. The trick is finding the crazy you can handle that can also put up with your flavor of jerkiness.
The scary stat to me is that half the people driving cars are dumber than average.
That said, real mental illness is no laughing matter. My childhood friend committed suicide in his mid-40s a few years ago, 6 months after he finally got married. He lived his whole adult life dealing with mental illness. I have had others with mental illness that I know as well. Some is chemical, but some is self-created and for others, they just got a bad set of circumstances that put them down a rabbit hole. As we (American Society) teach our children that there are no absolutes, you create your own truth and that they are victims, it will become worse.
