Anxiety causes constant worrying and fear. It is estimated that one fourth of people with ADHD also suffer from some type of anxiety disorder. Most people that suffer from anxiety know that the fears they have are unreasonable and do not fit the situation they are in, yet they feel helpless and unable to stop the fear.
Besides the anxious feeling, anxiety causes physical symptoms, such as, headaches, stomach aches, nausea, and irritability.
