Hi Linda,
I will be thinking of you tomorrow and hoping your bone scan goes well. In November I was where you are now. One mastectomy and node clearance, plus a couple of rounds of chemo later and I still find it hard to believe I'm doing this.
My tips for the early days is to plan treats for yourself so you have something to look forward to. A nice day out can be snuck into the program in between appointments. Before my surgery I wanted to swim in the ocean one day and also spend a day taking photographs at a location of my choice. I think my husband enjoyed those days as well. I felt sad but more normal and it got me away from hospitals and needles.
Take care.
