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.
The problem with catastrophizing is that it is rigid thinking. Suppose you worry that you’re having a heart attack every time you experience some chest pain. It’s usually easy for a health professional to distinguish between anxiety and a heart attack. But catastrophizing resists new information. Even though, your doctor has done tests in the past and has reassured you many times, you worry that this time will be different. Your exaggerated fear is preventing you from changing your thinking, and is keeping you stuck.
One of the most important things you can do is to listen to your family member or friend talk about the things in his/her life that are sources of stress. A first instinct might be to offer advice or ideas for a "quick fix". However, simply accepting your friend's stress levels can help them deal with their anxiety, knowing that they can rely on you as a source of support even when their symptoms might be tough to watch. Studies show that social support from family and friends can be one of the strongest protective factors against debilitating levels of anxiety.
I don’t know if I’m having anxiety attacks but every time I face a minor problem in my life, even if it us really stupid, I feel like I want to cry, to scream, and it’s like something is blocking my throat. I can’t control my anger during those moments, so I usually turn off my phone so I don’t say things I don’t mean to my friends or my family when I’m panicking and overthinking about any minor situation.
The emotional effects of anxiety may include "feelings of apprehension or dread, trouble concentrating, feeling tense or jumpy, anticipating the worst, irritability, restlessness, watching (and waiting) for signs (and occurrences) of danger, and, feeling like your mind's gone blank" as well as "nightmares/bad dreams, obsessions about sensations, déjà vu, a trapped-in-your-mind feeling, and feeling like everything is scary."
