Coughing up green gobs of goo? Ew. What is this, and how can I relieve symptoms until I can see a Doctor?

I have a deep, chest, bronchitis sounding cough. The phlegm produced is thick and dark yellow to greenish. I have a runny nose, but am not really sneezing. There is pressure in my chest, and I am having difficulty breathing. I don't sleep well b/c I am coughing so hard, and occasionally have coughed up blood and/or vomited due to the intensity. I have pressure in the area behind/around my eyes and nose. Also, I had these symptoms a while back, and thought it was just the common cold. It has been on and off for about 1 1/2 months. I would go to a doctor, but I do not have a primary care physician near my University. Does anyone have any ideas or suggestions??
