Another important prevention strategy for anxiety is to incorporate exercise into your daily activities. Exercise has been shown to decrease stress hormones that influence anxiety and also improve overall mood. Exercise can also help you disengage from worry and stress and focus on the current task of exercising. Exercises such as light jogging or brisk walking that can be incorporated into your daily activities can help reduce the impact of anxiety when it occurs.

Persistent and excessive fear of a specific object or situation, such as flying, heights, animals, toilets, or seeing blood. Fear is cued by the presence or anticipation of the object/situation and exposure to the phobic stimulus results in an immediate fear response or panic attack. The fear is disproportionate to the actual danger posed by the object or situation. Commonly, adults with specific phobias will recognize that their fear is excessive or unreasonable.
Genetics and family history (e.g., parental anxiety) may predispose an individual for an increased risk of an anxiety disorder, but generally external stimuli will trigger its onset or exacerbation.[57] Genetic differences account for about 43% of variance in panic disorder and 28% in generalized anxiety disorder.[58] Although single genes are neither necessary nor sufficient for anxiety by themselves, several gene polymorphisms have been found to correlate with anxiety: PLXNA2, SERT, CRH, COMT and BDNF.[59][60][61] Several of these genes influence neurotransmitters (such as serotonin and norepinephrine) and hormones (such as cortisol) which are implicated in anxiety. The epigenetic signature of at least one of these genes BDNF has also been associated with anxiety and specific patterns of neural activity.[62]
My grandparents, who I lived with my entire life, just passed away. One in june and the other in september. My girlfriend wants to spend the night with her sister and the thought of it scares me. I fear that I am pushing her away, thus for sending me into a state of anger at myself followed by a heavy cold sadness, panic and fear. Then I start to get a small headache, clammy feeling overcomea my body, I start feeling naucious and then the next thing I know, my girlfriend is waking me up trying to pick me up off the floor. Is this a simple anxiety attack that will go away?
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.

Please note that it is not a good idea to attempt to diagnose or label a friend or family member. Only a mental health professional can diagnose an anxiety disorder, as many disorders have overlapping features, and can go together with other types of mental health difficulties. However, if you notice signs of anxiety, or just feel that something is not quite right with someone that you care about, it's a good idea to reach out to ask the person how they are feeling. You could start with something neutral and supportive like, "It seems like you haven't been quite yourself lately. Is there something going on that you want to talk about?"

A condition in which parting with objects (e.g., household items or personal possessions) causes significant distress. In addition, many individuals continuously acquire new things and experience distress if they are not able to do so. The inability to discard possessions can make living spaces nearly unusable. Relatedly, the cluttered living space can interfere with the performance of daily tasks, such as personal hygiene, cooking, and sleeping (e.g., the shower is full of stuff, the bed is covered with clutter).
Furthermore, certain organic diseases may present with anxiety or symptoms that mimic anxiety.[6][7] These disorders include certain endocrine diseases (hypo- and hyperthyroidism, hyperprolactinemia),[7][73] metabolic disorders (diabetes),[7][74][75] deficiency states (low levels of vitamin D, B2, B12, folic acid),[7] gastrointestinal diseases (celiac disease, non-celiac gluten sensitivity, inflammatory bowel disease),[76][77][78] heart diseases, blood diseases (anemia),[7] cerebral vascular accidents (transient ischemic attack, stroke),[7] and brain degenerative diseases (Parkinson's disease, dementia, multiple sclerosis, Huntington's disease), among others.[7][79][80][81]

The symptoms of a panic attack may cause the person to feel that their body is failing. The symptoms can be understood as follows. First, there is frequently the sudden onset of fear with little provoking stimulus. This leads to a release of adrenaline (epinephrine) which brings about the fight-or-flight response when the body prepares for strenuous physical activity. This leads to an increased heart rate (tachycardia), rapid breathing (hyperventilation) which may be perceived as shortness of breath (dyspnea), and sweating. Because strenuous activity rarely ensues, the hyperventilation leads to a drop in carbon dioxide levels in the lungs and then in the blood. This leads to shifts in blood pH (respiratory alkalosis or hypocapnia), causing compensatory metabolic acidosis activating chemosensing mechanisms which translate this pH shift into autonomic and respiratory responses.[25][26] The person him/herself may overlook the hyperventilation, having become preoccupied with the associated somatic symptoms.[27]
A person with panic disorder experiences sudden and repeated panic attacks—episodes of intense fear and discomfort that reach a peak within a few minutes—during which time the individual experiences physical symptoms such as chest pain, heart palpitations, breathlessness, vertigo, or abdominal distress, sometimes accompanied by the fear of dying or of going insane.  These symptoms may seem similar to those of a heart attack or other life-threatening medical conditions. Panic disorder is often diagnosed after medical tests or emergency room visits have ruled out other serious illnesses.

Researchers have conducted both animal and human studies to pinpoint the particular parts of the brain that are involved in anxiety and fear. Because fear evolved to deal with danger, it sets off an immediate protective response without conscious thought. This fear response is believed to be coordinated by the amygdala, a structure deep inside the brain. Although relatively small, the amygdala is quite complex, and recent studies suggest that anxiety disorders may be associated with abnormal activity within it.
Antidepressants called selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly used as first-line treatments for anxiety. Less-commonly used — but effective — treatments for anxiety disorders are older classes of antidepressants, such as tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs).
