Do a lot of emphysema patients suffer from this? I have panic attacks==anxiety disorder, untreated. I read about it and next thing I thought I was going through it. I survived it....so I'm confused. I'm extremely anxiety ridden and keep freaking out. Went to the ER twice and was sent home! I thought I needed the hospital. They act like I'm a loon. Anyone know about this? Is it common or uncommon? Thanks! Oh, I'm pretty close to end stage...thus the anxiety and freaking out!
