When you are facing a task that overwhelms you the first thing you should do is to break the task up into a series of smaller steps or tasks. Completing these smaller tasks one at a time will make your stress more manageable and will also increase your chances for success.
Most people get stressed when multiple events occur at the same time. Instead of taking out your frustrations on your pets, you should take a deep breath and try to find a distraction for a few minutes to get your mind off of the problem. You could take a walk, read the newspaper, listen to some music or do an activity that will give you a fresh perspective on things. This mental timeout will help you to refocus on your current situation.
When dealing with anxieties, a person should learn to take things one day at a time. Do this instead of focusing on exaggerated assumptions that may or may not happen, always focus on the present and take it one day at a time.
Often I find that it helps to be able to talk to someone about my stressful situations. Talking to a trusted friend, counselor, or clergyman will not only make us feel better, but they might be able to offer advice and insights on how to best deal with your current situation. This is much more effective than yelling at your pets.
It is not always easy to deal with stressful problems and situations, however taking our frustrations out pets or other people will never make the problem go away. When things are not going right, just remember to treat your pet the way you would want to be treated.
