Hi Melissa
Rest assured there are no stupid questions. You will have more questions as you continue your treatment, and there will be people here happy to advise as Kath has already done.
Your comment about your oncologist struck a chord - after my first meeting with mine, I felt I had been run over by a bus. But I have learned to appreciate how thorough he is and his honesty - my situation is less difficult than yours but I much prefer to know the whole story, I have found it easier to cope when I know what the real challenges are (and the real options).
Best wishes to you and your family.
