When your To Do list is making you sweat, you probably just push on through anyways.
While this seems like a productive way to attack your responsibilities, you are actually creating more anxiety for yourself. As you continue to 'soldier on' with your responsibilities, your body creates more stress hormones, making you prone to react more aggressively to additional stress.
Think about it. When you're upset about something and then someone comes up to you with more bad news, you feel even worse about the additional news.
What you need to do is to stop the cycle of stress for a moment.
Whenever you feel as though you might explode, you need stop whatever you are doing and simply rest.
