I need hope

My mother called me on Thursday and told me that the biopsy that she had done came back positive for cancer and since that moment I have not stopped thinking about what is going to happen. She calls me her rock but I really feel like jello inside. I am having a hard time taking care of my two month old son, I just want to spend every minute with her. I know that until this tumor is out and we are on the path to curing this thing I am going to be walking into walls. I feel at times like there is everything to be hopeful about and then there are times when I can't help but to feel desperate.
