Newly diagnosed and in shock

Hi I've just been diagnosed with advanced adenocarcinoma of lung. Huge shock having been feeling fighting fit until beginning of June when I got what I thought was an exacerbation of asthma with a poss viral infection. Sent for cxr when not getting better swiftly followed by CT and suddenly I was a cancer patient. I think the speed it happened contributed to the sense of shock I still have. Had a tough few weeks with tests and having a pleural effusion drained twice. Feel very breathless and coughing a lot and still have to wait for tumour markers and to see an oncologist before have any idea on treatment. I just want things to move on faster now so I've got a bit more certainty. On the positive side I'm getting really good care and fortunate to have it on doorstep.
