I have not been a founder of any company so I can't comment on that part. But I can strongly related to this part - "what it would be like to work at Wal Mart, or the construction site outside, or as a bagger at a grocery store"

I am a passionate web developer but a few months ago, I had these exact same thoughts mainly about switching to a low stress job. Later I realised that I needed a break badly and the monotonousness of work ( building some kind of CRUD all day ) for me personally was making my life severely discomforting. So I left the job against everyone's advice and for the next few months I had terrible arguments with my family about this decision. But I was at peace the moment after I left the job and I think it was the right decision, even though my family wants me to regret it.

It's not that you hate what you do, but you definitely need a break and not just like a vacation, but actual handing over of responsibilities to someone else. After a few months, I felt like being back into the business and the optimism for work was back.

So this is probably against what everyone else is advising here but if you don't like it, leave it. Your wife should understand this too, if this is so important to you that it makes you cry. And definitely take up a stress free job for a change. It should help.

As far as leaving the company goes, you might find someone in ranks just below you who could be able enough to take over most aspects of your position.

Let me know, if you think this is a completely wrong advice.

I have these thoughts too, and then realise basically all jobs suck at some level. If they didn't suck, people wouldn't need paying to do them.

May be most do if you look at them from one person's perspective. The point here is to try something else for a change until you figure out whether you want to go back to doing something you liked earlier or moving on.
