((MikeDelta)) - sorry you're struggling with this. Have you spoke to your doctor or have a therapist? I read your 1st post here and often our emotions are related to deeper issues, like how we were brought up. When you're in this rage, what's the worst that would happen - is it tears or is there are chance you yell or physical? In your other thread you mentioned a drinking problem and unhappy parents. Often in cases like this, the child ends up stifling their emotions. It might be the boss reminds you of your mother, in respect to the criticism.

Not sleeping enough can make us less able to handle our emotions, so fixing this would be a good start. Healthy eating and exercise also helps with stress. Learning how to relax and simple deep breathing also helps. Filtering the negative thoughts is another tool but takes practice. For example, an "attitude" doesn't mean you're stupid or useless. Do you have designated time breaks at work, so you won't run into that misunderstanding? I understand how getting that flustered can be exhausting. If this is related more to you than a personal vendetta from the boss - try not to take it as a personal attack.
