You will be fine. Of course you will be stressed out. That's normal. Do you have someone to go with you? My mum always came. Yes I had radiation -6 weeks worth. Do you need to? I wasn't sick with chemo. It made me very tired for the first week. I would just stay in bed. Then the second week I would get some strength back and the third was really good. Felt pretty normal in that third week.
I think it's the waiting that's the hardest. And you hear all these horror stories but its amazing how strong you can be. And the will and determination to beat this. I just kept thinking if young children can go through chemo , then I can! There's always someone worse off and if they can do it, so can I. That's what helped me anyway. Good luck with everything. What hospital are you going to?
