Been here. It's the pits.
The more I see these kinds of posts (and I'm seeing them a lot lately), the more I think we need a community specifically for this stuff. Where we talk about the difficulties of entrepreneurship, and how terrible it gets. Where you must be this damaged to enter.
Because frankly, I don't think HN itself is the right place to talk about how many times I've tied a noose.
If I had more time I would start something like this.
