I trust from the title of your post, you are now in recovery and I hope that you are doing well.
Now that you have found this site, you need never feel alone - there is always someone here to answer questions, give advice or to give support when it's needed.
Still, that's the first stage over and let's hope that you get good news on Monday.
Isn't it strange how complacent we can become with life? We don't really appreciate what we've got until it's gone. One thing that a cancer diagnosis does is to make us appreciate how precious every single day is.
I am now 16 years since my first diagnosis, when I had a lumpectomy. Six months after that I was diagnosed with pre-cancerous cells in my other breast, then just under a year after my lumpectomy, I found another lump in my original breast. This time it was another cancer and I had double-mastectomy. Although not as active as I was pre-cancer, I still manage to lead a busy and fulfilling life.
I'm sure that you're not useless. It is difficult to accept that you have to rest when you're used to being at work, but, as you say, we just have to cope with the hand we're dealt.
