It sucks I know! I finished eight months of chemo in late Nov and just learned that I will have to start again within the next few weeks. NOT looking forward to going through all that chemo entails again!
I know this is easier said than done, but try to live in the moment and not think about the upcoming PET scan. Your not gettng a chemo treatment today which means you can get out there and enjoy life for today. I know that is what I am trying to do. In the back of my mind I know I will be starting chemo shortly, but I feel good today and I'm going to take advantage of that. If I live my life one day at time and not worry about tomorrow I will be able to get through this a second time and so will you if need be.
