You have to anchor yourself and what you want and learn to state where your boundaries are. I remember I was given a job that was too hard and the time constraints were too short and the software broke, etc. and I was right there on the urge of tears and the company executive vice president, who was normally not even remotely kind or thoughtful made a statement of fact, "If you can't do it, you can't do it!" absolving me of the responsibility I had taken on. Just because someone says, "Go, do this, NOW!" their wish is not your command. You have to learn to say, "I do not know how, I have not been trained to do that." Otherwise we are just taking on stress for ourselves? We have to know who and where we are and what we want/can do, etc. and stay with that, not just jump when someone else says, "Jump!" or we'll be more anxious and more depressed. If other people we work for are unreasonable we cannot stay healthy working for them so there is no point trying to please their unreasonableness, teaching them they might be able to get away with it?
