Depression, Fear, Social Anxiety, Generalized Anxiety, Panic Disorder, Phobias and OCD are some of the most common and uncomfortable physical, mental and emotional states that people may experience at some point in their lives. Depression can occur in short episodes, from a few days to a few weeks, or, it can be long-term, lasting months or even years. Many people experience loss of energy and motivation, low self-confidence, and negative thoughts. Although there are many different types of anxiety, there are a few common signs and symptoms, such as fear of the future, tensions, and difficulties concentrating, that indicate you may be suffering from more than a passing wave of anxiety.
