Wow! I can feel your pain reading yours and other people's responses. I don't blame you for feeling a bit sad. Sometimes those we expect to stand by us are the ones who don't. I was very lucky to have the support of my family before and after my treatment. The brothers admittedly didn't have as much to say as the sisters, but they were definitely there for me. Some of my friends however drifted away which was sad. I know some people have trouble dealing with the big C. However I just don't get them not supporting you on your walks etc.
I send you a big hug and hope Christmas can be peaceful for you no matter how you spend it.
