COPD/EMPHYSEMA with SOB and Vomiting

Hello, I'm 42 years old male. 18 months ago I had the right top lob of my lung removed due to shortness of breath and fatigue but now I think my breathing is worst. When I have shortness of breath my airwave cut off and all I can do is vomit. The vomit does not come from my stomach but all the flem in my airwave. I vomit this stuff up anywhere from 2-6 times per day. There are times I get shortness of breath from just sitting or talking on the phone. The Doctor who did my right lung is talking about taking my left top lob. I'm not sure if I can go thur it again and scared I may even be worst after it's all over. I'm so scared that I have put a wall up between my health conditions and the Doctors. My father died when he was 46 due to lungs failure. Not sure where to turn at this point. I was supposed to get a MIR and see the Lung Specialist in Oklahoma City at OKLAHOMA UNIVERSITY HOSPITAL but I got scared and never went and never went back. At this point I'm sure what to do. Does anyone here have SOB with Vomiting?
