Hi Temple I can relate to your post completely. I found some of the staff very off hand and the rad process freaked me out too. It is very intimidating your lying on a hard plastic "bed" with (in my case) both boobs exposed and a machine slowly moving around you making odd noises. I hated it. I decided that having breast cancer treatment was like having a baby no privacy and no dignity you just have to get on with it. The staff are of course just doing their job but when you are feeling so low and vulnerable it is hard to get past the shit stuff.
But hang in there while it is shit you do get use to the routine and on my first day I told the staff that I was very nervous and apprehensive and they were very kind.
Big hug to you.
Keep busy. You will get through this!
I hope all goes well for you next week.
