My health has been going down hill completely in the last 2 weeks. It started with food poisoning to the flu? to now my ulcer symptoms are reappearing. Around 6 every night my throat feels like it's swelling up and it's hard to breathe. I have no appetite and no desire for sleep. I feel nervous tension and my heart feels like it's beating irregurily. I wake up every morning so stuffed up I can hardly breathe, I'm coughing up yellow stuff in the morning and at night. I seriously feel like I'm falling apart. What is wrong with me?
