Repost: Ethical question: What to include or not to include on resume?

I am redoing my resume looking for a new job in a different field. I have always just assumed that I should never leave out a job on my resume because that might look dishonest, but I have just been talking to someone who used to be in the human resources field, and she disagrees. She says that everyone has things they leave off to present themselves in the best light. Basically, the resume is to get your foot in the door, and you can tell them the other stuff later, which I would!

This is the one she says I should leave off. Years ago, I took a job that I only stayed with a short time. I knew it would be a stressful job when I took it. The reason I left was that I was physically completely exhausted due to not only the stress of the job, but also some undiagnosed minor medical stuff, which is now controlled with medicines. I simply was not able to do my best, and I felt that it would be better for someone else to do this. I didn't find out about the medical problems until actually a couple of years later. I have had other positions since then, in fact, I had other jobs before I found out about the medical stuff, but they weren't as stressful physically demanding as the one I left. I did give my employers notice and enough time to replace me, and I made it a point to have all my responsibilities completed and up-to-date when I left. I didn't do ANYTHING wrong here, I just was a walking zombie!

I really would prefer to leave this job off, as the short time period doesn't look good, but I certainly don't want to lose a future position because they think I was dishonest! I definitely would not leave it off the official application for whatever I was applying for.

I want to present myself in the best light, but I don't want anyone thinking I was being deceptive. What do you think?
