Dear Welcome to HCM We understand your concerns I went through your details. I can understand. is simply a reaction to a stimulus that disturbs our physical or mental equilibrium. A stressful event can trigger the “fight-or-flight” response, causing hormones such as adrenaline and cortisol to surge through the body. A little bit of stress, known as “acute stress,” can be exciting—it keeps us active and alert. But long-term, or “chronic stress,” can have detrimental effects on health. Stress and anxiety usually increases heart rate, makes you to breath faster, stretch muscles, aches many part of body, hibernates many unnecessary processes of body including digestion etc. These actions are necessary and part of fight or flight syndrome. Because of the above actions of the hormones, breathing issues are possible. In fact these are not breathing troubles. Your body asks for more oxygen. Just close your eyes and breath shallow and relaxed. Your anxiety will subside. You may also consult a psychologist for further advise.
