This whole cancer thing really sucks! I couldn't imagine living without my mom and i am 24. I also have a 3 year old son who has heard me crying every night for the last week since we found out about my mom. I don't know how to explain it to him either. I guess just be honest and make the most out of the time you have. And fight the cancer to the very end! But your right it is crazy because my mom is not sick either! She almost didn't even have her gallbladder out. And now she has cancer. But the doctors could be wrong. You might have a lot of years left in you. But one thing that I would do if i were you, is to start making tapes or letters for your child. Something he can open from you on special occasions. I have heard of other people doing that before. But how can you only have a year left if your not even sick? Get another opinion. I will be praying for you.
