Dear Meghna Welcome to HCM We understand your concerns I went through your details. Panic attacks, panic disorders are always due to underlying anxiety disorder or stress disorder. You need to understand the stress and anxiety problems you are undergoing. You mentioned you are travelling alot and need to adjust with verity of situations while you are doing your education. I appreciate that. The stress related to that travelling, frequent adjustments and body and mind s inability to cop up with the frequent adjust-mental pressures must have triggered the panic button. Stress is simply a reaction to a stimulus that disturbs our physical or mental equilibrium. In other words, it s an omnipresent part of life. 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. You may not be able to control the stressors in your world, but you can alter your reaction to them. Physical exercise, creative activities, deep breathing, being away from the situation for sometime etc can help you tackle the stress. I suggest you to consult a psychologist / psychiatrist for diagnosis and further treatment. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
