why don't I feel that this is serious?

Hi LynnW ..... I don't think there is any right or wrong way to feel when diagnosed with breast cancer and going through the subsequent treatment. Perhaps at the moment you are so busy going through all the phases of treatment that you are just taking a day at a time.  Perhaps also you are a little numb and maybe you will feel something more down the track - or maybe you won't.  It seems however that you are worried about the fact that you aren't worried .... if that makes sense.  Every woman's journey is an individual one and no-one can tell you how you should feel.  Why not have a chat with one of your doctors about how you are feeling - or not feeling?   Don't be too hard on yourself.  It's your journey to travel in whatever way works best for you.  I found I kept it all together pretty well during treatment.  I became more emotional after my treatment; probably because during treatment I was so busy and afterwards I had time to reflect.  All the best for your forthcoming chemo and radiation.  Kym x
