Hidden frustration is kept out of sight; it's concealed. It's an upset or annoyed feeling, especially when something can't be changed or accomplished. You get frustrated when your expectations don't manifest. An action or effort that fails to yield the results you expected. Sources of frustration exist both internally and externally. Daily stressors at home, at school, at work, and in relationships can lead to frustration. However, it can also be more severe and have a serious impact on your health. It is imperative to be mindful of your behavior and emotions and take the necessary steps to prevent frustration from escalating.
