Roller Coaster

I feel like I'm on a roller coaster ride. Unlike Space Mountain, I don't like this roller coaster. So far everything has been going really well. Until yesterday. I feel like my whole world has been turned upside down. Again. I went for a CT scan on Tuesday, and yesterday I got my results. The lymph nodes in my left groin area are enlarged. It is right near the area they removed 15 other lymph nodes. So now I have to go for another PET scan. It's possible I may have to have another surgery to remove them. I hope they turn out to be nothing, but I have at least a week before I find that out. It's the not knowing that kills. Everything seems to be going fine, and now this. When the "Why me" part of my life was gone, here it is again. Why me?
