Hi how are you? I have read your concern. Stress is among the major factors responsible for majority of health hazards these days. Anxiety and depression usually result when one takes undue stress in their busy lives. I suggest you to get relax as soon as possible to combat these symptoms. More than 50% of pain and discomfort goes away when we do relaxation exercises. You are young and exercise can make you stronger and calmer reducing stress. Join gym and increase work out slowly. Furthermore, an evaluation of chest pain by your medical specialist is essential in case your heart is undergoing any changes due to stressful life episodes. I will not recommend any medication at this stage. Just change your lifestyle, eat healthy diet and make exercise your routine.
