I'm sorry to hear about your diagnosis and that you're having difficulty finding support. I was diagnosed in October of 2010 and for me, it took a good year to feel like I was back on my feet emotionally. My support, other than family & friends has been online communities - mostly this one, but also most recently WTF (Where's the Funding?) for Lung Cancer (www.wtflungcancer dot com). Also, Being Cancer, Lung Cancer Alliance, and GRACE (all of which you can google). There are a lot of us out there who are going through or have gone through the same things and who are more than willing to offer advice and support.
This is the toughest thing I've ever had to do, but it can be done.
We're here to help as much as we can.
Warmest thoughts & prayers,
