<s>[INST] Hello doctor, i am a  female,25 indian... mostly i feel heavy at my chest.. feel like i need to struggle a lot to breathe.. was to doctor and they took all possible tests and told me that everything was normal and it is only  my thinking.. probably because i am over stressed...  for the past two days i am feeling the same thing.. can you please suggest me what to do..... [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Since all your reports are normal, no need to worry about major heart and lung diseases. Sometimes undiagnosed stress and anxiety can also cause similar symptoms especially in young individuals. So consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor. Don't worry, you will be alright with counseling and anxiolytic  </s>
