My friend and I were bullied by our bosses (in a very similar way) and now we commiserate over our shared "post bullying syndrome". We tend to be paranoid and more easily upset about things. Personally I just see it as being more aware of the things that go wrong that lead to a bad situation.

I had a new employee come in once and she lost her mind about something that I did know... she actually called a manager of mine (which was inappropriate) I wasn't angry then but I told her in no uncertain terms when I got back to my desk that I was aware of the issue, I had been doing the issue for at least 4 years prior to her arrival and there was no need for her to check up on me.. I had bosses of my own.

That shut her up.
