The theologian Paul Tillich characterized existential anxiety as "the state in which a being is aware of its possible nonbeing" and he listed three categories for the nonbeing and resulting anxiety: ontic (fate and death), moral (guilt and condemnation), and spiritual (emptiness and meaninglessness). According to Tillich, the last of these three types of existential anxiety, i.e. spiritual anxiety, is predominant in modern times while the others were predominant in earlier periods. Tillich argues that this anxiety can be accepted as part of the human condition or it can be resisted but with negative consequences. In its pathological form, spiritual anxiety may tend to "drive the person toward the creation of certitude in systems of meaning which are supported by tradition and authority" even though such "undoubted certitude is not built on the rock of reality".
"Anxiety" is a general term that describes a variety of experiences, including nervousness, fear, apprehension, and worry, that are common in several mental health disorders. While most of us have anxiety at some time, this is completely different from an anxiety attack or anxiety disorder. Normal feelings of nervousness, worry, and fear often have a known trigger (a major exam, money issues, or seeing a bug). But when you're having a full blown panic attack or anxiety attack, the symptoms — chest pain, flushing skin, racing heart, and difficulty breathing — can make you feel as though you're going to faint, lose your mind, or die. The reality is, you won’t. The key to surviving is to learn all you can about anxiety attacks and practice the skills you need to get through them.
Additionally, there is some evidence that Acceptance and Commitment Therapy (ACT), Mindfulness-based Stress Reduction treatment (MBSR), as well as online and computerized treatments are effective in treating panic disorder (Arch et al., 2017). However, the overwhelming majority of research supports the long-term success of CBT for treating panic disorder. More research is needed to explore the extent to which MBSR and ACT work when compared to CBT and other treatments, but preliminary results are positive. In general, empirically-supported treatments that are founded on the basis of research within the psychological and medical fields are recommended for treating panic disorder.
Biological causes may include obsessive compulsive disorder, Postural Orthostatic Tachycardia Syndrome, post traumatic stress disorder, hypoglycemia, hyperthyroidism, Wilson's disease, mitral valve prolapse, pheochromocytoma, and inner ear disturbances (labyrinthitis). Dysregulation of the norepinephrine system in the locus ceruleus, an area of the brain stem, has been linked to panic attacks.
Psychotherapy. A type of psychotherapy called cognitive behavioral therapy (CBT) is especially useful as a first-line treatment for panic disorder. CBT teaches you different ways of thinking, behaving, and reacting to the feelings that come on with a panic attack. The attacks can begin to disappear once you learn to react differently to the physical sensations of anxiety and fear that occur during panic attacks.
Cognitive therapy and exposure therapy are two CBT methods that are often used, together or by themselves, to treat social anxiety disorder. Cognitive therapy focuses on identifying, challenging, and then neutralizing unhelpful or distorted thoughts underlying anxiety disorders. Exposure therapy focuses on confronting the fears underlying an anxiety disorder to help people engage in activities they have been avoiding. Exposure therapy is sometimes used along with relaxation exercises and/or imagery.
