That's great that you have a plan @Jenny004s. I had a full mastectomy nearly 5 weeks ago and I was back at work and driving after 2 weeks. No family history - same as you.
Who knows why this bugger of disease picks us - but hey, we're in excellent company with an incredible support network and the beneficiaries of decades of research.
Don't hesitate to jump on here at any time and ask whatever you like. I asked some questions that really seemed quite trivial but they were things I wanted to know, and there was always an angel on this forum who was happy to give me their incite.
Best of luck with it all and please let us know how you go! xxxxx
