I don't think I ever had anger over it. However, it is certainly normal and many people do.
One of the things that helped me was research and this site's predecessor. At my first diagnosis the predecessor to this forum was on webcafe. I learned a lot from others and especially learned that if I was rigorous in my follow up that I would probably not die from bladder cancer.
So...since I didn't have to die from it, I figured what's the point of being angry about it. That's how my mind works. I mostly don't worry about things because if it then never happens, I spent all that time worrying. Even if something (such as a recurrence) were to happen, I figured why spend the time I had without recurrence messing it up by worrying.
That's my philosophy, but it would not be honest to say that I did not have down times in my thinking about this. When I failed BCG, I did get pretty reflective and quite sad.
What helped me most was knowledge. That also does not work for everybody. Some people study things and only retain the knowledge of the worst possible outcome and become convinced that is what will happen to them. That's not healthy.
We all have our own ways of dealing with things like this. Folks we tell also all have their own way of dealing with the news. Keeping that in mind helps a lot (in my opinion). Just because someone deals with things differently doesn't mean their way is wrong and it doesn't mean their way won't change with time and knowledge.
As I've been known to say "You're mileage may vary".
Positive attitudes create positive chemical reactions in the body. My blood type is B+ (BE POSITIVE) so I guess it's just my nature.
It's very ok to be angry though. Kick a pillow, punch a mattress, cry, or whatever to get it out. Whenever you can, think about how you want each day to be. You don't want to waste too many days being consumed by anger and/or fear but you will have some. It takes conscious thought to be happy, enjoy others and keep putting one foot in front of the other, but for me it has always been worth it.
I'm cancer free for 13 months and plan to stay that way. If it does come back or I get a new kind of cancer or something, I will deal with it when it comes. That's how I look at things but we are all different and that's what makes the world an interesting and wonderful place.
