It looks like you have pneumonia. Other than that, I do not see any problems. You are probably under stress from changes at work, and the stress causes headaches, upset stomach, and sleeplessness. For now, try to relax and exercise. It may solve your problems. Come back to see me again if the symptoms persist, and I will do further tests. I am going to give you a prescription for your pneumonia. Are you allergic to any medications?
