The theologian Paul Tillich characterized existential anxiety[23] 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".[23]

Not everyone understands is that someone with an anxiety disorder cannot "just let things go". This makes the struggle with an anxiety disorder even harder, and may prevent one from looking for help. However, it is very important to talk about these anxieties with someone and preferably find a health care professional as soon as you experience these symptoms. Anxiety should be considered as severe as a physical disease; however, most people in society do not appreciate the severity of this disorder. Some people may consider anxiety a fault or a weakness; however, it may help if people realize that many research studies have demonstrated biological explanations for (some of) the symptoms observed in anxiety disorders. Brain scans have demonstrated brain abnormalities in certain anxiety disorders, and also altered brain functioning has been demonstrated for individuals with anxiety disorders. Furthermore, there is some evidence that anxiety disorders might be linked to chemical imbalances in the brain.
Repeated and persistent thoughts ("obsessions") that typically cause distress and that an individual attempts to alleviate by repeatedly performing specific actions ("compulsions"). Examples of common obsessions include: fear that failing to do things in a particular way will result in harm to self or others, extreme anxiety about being dirty or contaminated by germs, concern about forgetting to do something important that may result in bad outcomes, or obsessions around exactness or symmetry. Examples of common compulsions include: checking (e.g., that the door is locked or for an error), counting or ordering (e.g., money or household items), and performing a mental action (e.g., praying).
Guys, I am 23 and this might sound very stupid but i recently broke up with my boyfriend of 7 months(yes quite a less time to experience anxiety issues but yes..) One fine day he just comes over and says its done between us.. I have fell out of love and thats why I cant pretend to be with you. It happened on 17th of this month i.e. 17th july and for over a week i couldnt sleep, eat food and I was nauseaic and I am still in a bad state.. I am forcing myself to sleep, to not think about it but my attacks starts early in the morning and get suffocated and want to just run out of the space. I get urges to calling him, speak to him, tell him how much I love him and miss him but its all like I am speaking to a wall. And i dont trouble my parents with this problem. should i visit a counsellor or should I give myself some time to heal ?
Anxiety disorders are associated with chronic life stress. Unpredictable, unrelenting, unresolvable stressors chronically stimulate the stress hormone system and cardiovascular system, and lead to states of constant increased activity. Biologically, the body has evolved to deal with imminent and concrete danger in the environment, rather than continuous stressors. Under normal conditions where chronic stress is low, exposure to a sudden threat activates the autonomic nervous system, i.e. increased levels of adrenaline and faster breathing, and racing heart rate. These reactions in turn trigger activation of stress hormones, such as cortisol. One of the effects of these stress hormones is to increase glucose levels in the bloodstream in order to respond to the imminent threat, so that muscles can be activated for the flight or fight response. Another effect of stress hormones is to supress the immune system, since processes such as healing and repair can wait until after the threat subsides. However, in someone with an anxiety disorder, where there is constant activation of these responses to everyday stressors, the stress hormone system loses its ability to control immune function, thus contributing to heightened systemic inflammation that increases risk for cardiovascular and even autoimmune disorders. Neuroscience and clinical research continues to investigate how anxiety disorders increase individual risk for developing physical health co-morbidities in hopes of identifying new treatments that may alleviate suffering from and prevent the development of these whole-body disorders.

Panic disorder is a condition that causes many disturbing mental, physical, and emotional symptoms. Despite these intense symptoms, panic disorder, panic attacks, and agoraphobia are all treatable conditions. Given that agoraphobia typically develops within the first year a person begins to have abrupt panic attacks, it is important to seek out help early on. However, treatment can provide much improvement, even for those with long-term symptoms.

As with most behavioral illnesses, the causes of panic attacks are many. Certainly there is evidence that the tendency to have panic attacks can sometimes be inherited. However, there is also evidence that panic may be a learned response and that the attacks can be initiated in otherwise healthy people simply given the right set of circumstances. Research into the causes of panic attacks is ongoing.
A phobia is an unrealistic or exaggerated fear of a specific object, activity, or situation that in reality presents little to no danger. Common phobias include fear of animals (such as snakes and spiders), fear of flying, and fear of heights. In the case of a severe phobia, you might go to extreme lengths to avoid the thing you fear. Unfortunately, avoidance only strengthens the phobia.
Some of these symptoms will most likely be present in a panic attack. The attacks can be so disabling that the person is unable to express to others what is happening to them. A doctor might also note various signs of panic: The person may appear to be very afraid or shaky or be hyperventilating (deep, rapid breathing that causes dizziness). Anxiety attacks that take place while sleeping, also called nocturnal panic attacks, occur less often than do panic attacks during the daytime, but affect a large percentage of people who suffer from daytime panic attacks. Individuals with nocturnal panic attacks tend to have more respiratory symptoms associated with panic and have more symptoms of depression and of other psychiatric disorders compared to people who do not have panic attacks at night. Nocturnal panic attacks tend to result in sufferers waking suddenly from sleep in a state of sudden fright or dread for no known reason. As opposed to people with sleep apnea and other sleep disorders, sufferers of nocturnal panic can have all the other symptoms of a panic attack. Although nocturnal panic attacks usually last no more than 10 minutes, it can take much longer for the person to fully recover from the episode.
With regard to environmental factors within the family, parenting behavior can also impact risk for anxiety disorders. Parents who demonstrate high levels of control (versus granting the child autonomy) while interacting with their children has been associated with development of anxiety disorders. Parental modeling of anxious behaviors and parental rejection of the child has also been shown to potentially relate to greater risk for anxiety. Experiencing stressful life events or chronic stress is also related to the development of anxiety disorders. Stressful life events in childhood, including experiencing adversity, sexual, physical, or emotional abuse, or parental loss or separation may increase risk for experiencing an anxiety disorder later in life. Having recently experienced a traumatic event or very stressful event can be a risk factor for the development of anxiety across different age groups. Consistent with the notion of chronic life stress resulting in increased anxiety risk, having lower access to socioeconomic resources or being a member of a minority group has also been suggested to relate to greater risk.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
