Anxiety is a normal response to a situation in which we experience one or more stressors. Anxiety prompts us to seek a safer, more familiar, more comfortable environment or situation. Often, however, anxiety becomes excessive.
When this is the case, one may know that a situation is not dangerous, but cannot help feeling frightened or engaging in behaviors that may feel impossible to control. Consequently, people with significant anxiety may avoid the people or situations they perceive to be associated with the anxiety.
