output: hello well from the information it appears you have an acute stress reaction but I need more data before reaching that conclusion as you are experiencing breathing problems on lying down and blood in your stools did you experience similar symptoms in the past do you have any past medical history are you feeling stressed out due to exams breathlessness on lying down persists for how long and how is it relieved do you use any recreational drugs and most important of all do not take any drugs like modafinil without prescription it could be dangerous do you experience these symptoms during each exam because it appears your symptoms are related to stress and anxiety of exams please tell everything hide nothing it will be confidential
