Sorry to hear that too Roy, seriously hope they can do something for you. I would echo Robbo's thoughts and say that whatever happens could always be turned around as a positive.
I can totally appreciate how your feeling and what your thinking. 11 years ago and on her 17 birthday my wife, Caroline, was diagnosed with an osteosarcoma (bone tumour).
They told her that not only did she need to start Chemotherapy but also some of the bone and her knee had to be removed and replaced with a Titainium femoral replacement and an artifical knee, but at worst they may have to remove her leg altogether. After a long hard battle she beat it and came through the other side a much stronger person with an unbeatable inspirational attitude on life.
11 years later she is cancer free but still in constant daily pain which is getting worse, she knows the day will come when her consultant will tell her that she has to have the leg off. As she always says when that day comes, she will learn how to run, do a skydive, join me on the high board and dive off and just basically do all the things that she can't and is not allowed to do.
Guess what im trying to say mate is that however bad some news or situation can be you can beat it and turn it around to make it work for you. You've got the support of you family and the support of many many people from here, some like me that you haven't even met face to face.
Keep the faith eh old boy. :thumbup:
