Sorry to hear your news, bandolin. I'm at the age where a lot of friends and people I know have had cancer of one kind or another. All of them have survived (touch wood). One friend has had 5 different types of cancer over the last 25 years!! She just laughs about it now, says "well, it's no mystery what I'll die of eventually". Depression is a side-effect of any life-threatening condition, you suddenly have to come to terms with the fact that you're not immortal. So, like Quest says....be prepared for it, and recognize it when it starts happening.
