I'm about to start radiotherapy and chemotherapy for throat cancer. I'm so scared! I have to have a RIG tube fitted for when I can't swallow any more and I am irrationally terrified of a tube down my nose during the procedure. My other phobia is dental work- spent most of my 3 extraction appointment having a panic attack. 

Any advice on managing a RIG gratefully received. Any advice on panicking less about everything...I've never randomly cried so much in my life!
