> Each morning for the past couple months, my first thought has been "What could today be like if I didn't work here?". I drift off into exploring what it would be like to work at Wal Mart, or the construction site outside, or as a bagger at a grocery store. It seems so stress free.

Here's the thing- it probably isn't stress free, just different kinds of stress. And you also need to ask yourself whether the feelings are caused by your job and stress, or if they're just coinciding with them.

As many others have said, look into talking to a therapist.

Also, talk to you wife about this! If she was crying the same way, you'd want to know, and you'd want her to trust you enough to tell you. If there's any person you need to be able to open up to, it's your spouse.
