Anxiety disorders often go hand in hand with depression and other mental illnesses. People who have anxiety disorders struggle with intense and uncontrollable feelings of anxiety, fear, worry, and/or panic. These feelings can interfere with daily activities and may last for a long time. Would you know the telling signs if it were to happen to you or someone you loved?
The signs could easily be taken lightly and go undiagnosed. Mental illnesses are conditions that affect a person’s thinking, feeling, mood or behavior, such as depression, anxiety, bipolar disorder, or schizophrenia. Such conditions may be occasional or long-lasting (chronic) and affect someone’s ability to relate to others and function each day.
