I'm tired of people making me feel guilty for taking a new job! It makes me feel horrible. Can anyone relate?

My first job out of college was working at a large defense contractor. I had to quit after three and a half months because I couldn't handle it. All the stress induced a mixed episode.

When I gave my two weeks notice, both of my bosses (yes, I had two) kept making snide remarks. Or they gave attitude like: "Well, looks like we're going to have a HUGE HOLE because SOMEONE is leaving..." Or one of them said "Well, Steve, I GUESS you'll have to do extra work now" while looking at me! I was always productive. I never dragged my feet or anything. And I most certainly didn't give anyone disrespect. So it's not like I was a worthless asshole employee.

Now I'm changing jobs again (because the stress has been f_cking with my mood), and my boss didn't say anything. Next thing I know, all of my work was given to someone else without telling me. Obviously someone else will have to pick up the work, but no one told me anything. I was trying to close things off, but nope, they just said, "Don't worry about it." Maybe I'm interpreting things wrong, but I start my new job on April 1st, so I DEFINITELY have time to close things off. I've only f_cked up a handful of times, and my boss told me before that I was a "valuable member of the team". So what the hell is the "don't worry about it" attitude coming from?

Jeez. Some people are so resentful.
