Hey @Dawnc,
Congrats on nearly being done. Hopefully the rads won't give you any trouble.
You are more than welcome to complain and rant. Sometimes you just need to get it out of your head. The highs and lows ebb and flow the whole way along. You are correct, sometimes it just feels like someone else is driving and you don't have control. It will get better after you're done. It takes a while but you will get back to you.
Rest if you need to don't rest if you don't. There is no right or wrong way you just have to muddle through as best you can until you come out the other side.
Hope you feel better soon.
