Hey Snowie!
I think its so normal to feel a bit overwhelmed and to also be thinking ahead of things. Just to ease your mind, Radiation is in no means anything like Chemo. It literally takes minutes to do, takes you longer to get there and get home, it is completely painless, like having a scan. The only thing I can say is, it is cumulative, so it causes fatigue as you go, saying that I worked full time through it and am a single parent. However at the end of the 6 weeks, I had to have 2 weeks off as the fatigue was debilitating and I am fair so ended up with radiation burn to the breast and armpit, it healed super quickly however with burn gel they provided. So I feel you'll manage fine getting there and home, you just may feel tired as it progresses. So take it a day at a time, and if you feel you're struggling, have a look at how you can get some help. The medical team are so helpful honestly, dont be scared to ask for help or any questions.
You'll surprise yourself, you'll do great!
Hugs Melinda xo
