Hey @Heton,
CONGRATULATIONS! One more hurdle out of the way. It's odd how we get a bit lost after treatment. Mind you I didn't have that feeling after chemo. I jumped up and down for joy. Gave the nurses some flowers and chocolates said see ya and just about skipped out to the car.
I did get that same floating in limbo feeling a couple of weeks after my last rads appointment. It's normal and will get better as you regain your strength. Don't be surprised if it takes a little bit of wading through and processing what the heck just went on and where you go to from here.
Welcome to survivorship.
All the best lovely.
