Bless you, it is a dark and worrying time. That's completely natural and normal. Try to focus on the fact that it's been caught relatively early and success rates are high at this stage.
Your treatment sounds the same as mine. I had 1 chemo session per week and radiotherapy every day (excluding weekends) for 5 weeks. This was followed by an inpatient stay for 4 nights for the brachytherapy.
Take lots of entertainment (books, TV progs) for the chemo days, as they are long and boring. In the end I only had 2 chemo days, instead of 5, as I developed tinnitus and they were worried it would cause permanent hearing damage, so do flag that up to your oncology team if that happens to you (tinnitus is quite common, apparently).
They might give you crap anti-nausea meds on your first chemo session. If they don't work very well, speak to them at your second chemo session and ask for better anti-nausea meds.
You will probably go off rich foods, so try to keep quite plain foods available to you at home.
The radiotherapy doesn't hurt and doesn't last very long. You will probably start to feel the effects of it from about 2 weeks after you start. Just get lots of rest (I hope you can take time off work?) and stay hydrated.
The brachytherapy can be tough, but you will get through it. Then about 2+ weeks after your treatment ends you should start to feel more normal again.
I wish you the best of luck and hope for a positive outcome! X
