It's such a personal choice. I know what you're going through.
I jumped straight into chemo within days of meeting with the Onc. I do question my choice now & again as I got a clear margin in my lumpectomy. You too? But when i find myself questioning my choice it's linked to the control factor. I like control too!! :-)
I am single & 39, no kids, great job, extremely independent (fiercely so) and I was actively dating and having a blast before all this happened in May. The last thing I want is to be bald and on the shelf for the next few months & end of my 30's. But my 30% chance of recurrence reduces to <10% by doing chemo. My brothers both like a bet on the races and they are odds they would both jump at!
I hope my raving on about me in this reply helps rather than hinders. I know for me, I find it helpful to hear how others on here made their choices & decisions & that it's natural to 2nd guess or back pedal. This is major stuff.
I also found a 5mg valium on the morning of the chemo (FEC) did wonders to settle my mind and allow me to calmly take it all in and see how it all works, rather than sit there and have it "done" to me.
Let us know how you go with your decision, dont be too hard on yourself either way x
