Stress can come from any situation or thought that makes you feel frustrated, angry, or anxious. What is stressful to one person is not necessarily stressful to another.
Anxiety is a feeling of apprehension or fear. The source of this uneasiness is not always known or recognized, which can add to the distress you feel.
Stress is a normal part of life. In small quantities, stress is good -- it can motivate you and help you be more productive. However, too much stress, or a strong response to stress, is harmful. It can set you up for general poor health as well as specific physical or psychological illnesses like infection, heart disease, or depression. Persistent and unrelenting stress often leads to anxiety and unhealthy behaviors like overeating and abuse of alcohol or drugs.
Certain drugs, both recreational and medicinal, can lead to symptoms of anxiety due to either side effects or withdrawal from the drug. Such drugs include:
A poor diet -- for example, low levels of vitamin B12 -- can also contribute to stress or anxiety. Performance anxiety is related to specific situations, like taking a test or making a presentation in public.
