Sounds similar to me. I started chemo last week and so far managing to work. Yes I would love my old life back of worrying about family stuff, I feel like I always did appreciate the little things in life and didn't need a 'wake up call' about life. But hey ho here we are...
Today is my cancerversary. It's exactly one year today since my diagnosis. I am alive. I am grateful. Here's my story: http://lifeafterlola.blogspot.co.uk/
No wonder you are still in shock from your diagnosis which is probably making you think and feel the way you do now.
Many women survive long term and do not get a reoccurance. It's also worth bearing in mind that many won't be posting on the forum years after their treatment, since they may no longer feel the need!
Have you spoken to your oncologist about your prognosis, obviously it's a very personal thing, we are alll individuals rather than statisitics, and type of cancer, stage, general health can all be factors.
While you are waiting to hear from long term survivors I can say I am nearly 4 years on post diagnosis (in early 40's when diagnosed, moderate lump, had single node biopsy, not in lymph glands), no signs of reoccurance (although I had a brief scare which turned out to be old fractured ribs).
Last summer I singlehandedly laid a sandstone patio and apart from a few side effects from hormone therapy am pretty much normal *whatever that may be!). I should add I did not have chemo (they decided not in my case, but later said I was borderline re chemo).
Be kind to yourself, your first chemo, it's natural that your mind will be spinning.
