I usually just didn't think about it and went about my living life normally. I think there were a couple of times the day of the cysto that I'd worry.
I'm not normal though.... (my wife tells me this all of the time).
My philosophy is that I don't want to waste any time worrying about things. If I worry and whatever it is I'm worried about happens, then worrying didn't do any good. If I worry and it doesn't happen, I've wasted part of my life worrying.
In any case, even people at work can't understand how I do this. When I had the cancer diagnosis, they couldn't figure out how I just went on as usual and even joked about the cancer. They said they'd be worried sick. I certainly understand their point but it's just not for me.
I enjoy being fat, dumb, and happy. It's worked so far and I'm sticking with the plan.
