Hi SLD
I know it's probably not what you wanted to hear today, but I had a double mastectomy just over six months ago and I'm already back playing football :) . Like you I had only my partner for support and of course the kids! (My family are overseas). Oddly being home from work for an extended period, I got to spend a lot of time with them and that was a real highlight for me.
My advice, cry lots, take the drugs and hug your kids.
Good luck with the next part of your journey, you'll be out the other side before you know it
