Hi there... I've had lots of all scans but not for head or neck so not sure if that makes a difference, but if it's the one that sounds like a workmans drill, i was in there for ages (or so it felt) and they let me take in a c.d in and they played Westlife (I know) etc and I'd trained to zone out and to it, and it really helped me , asked them to play it loud as poss... don't know if they can do that wear you are, but worth an ask ... maybe not to West life, a .... hope that may help ... best wishes for 2018, hope it's kind for you xx

The workman's drill lasting for ages sounds like an MRI scan. And there's nothing wrong with Westlife!  I never thought to ask for them to turn up the volume. 

How did you train to zone out? That sounds like a useful skill :)  

Hi again ... glad West life didn't make you laugh .. what I do often when thoughts try to get into my head is go on u tube and put in meditation and there's good ones and bit wacky ones but if you can find a good one esp at early hours when I can't sleep, i put earphones on and listen to it while feeling comfortable and concentrate till those other sad / scary thoughts drift away ... I do it often till l can zone out lol ... the more you do it , the easier it becomes ... 

I also read a book by Paul McKenna and one bit he says is when you have sad / angry thoughts esp when you loose someone and it's overwhelming,  remember the best funniest memory you have and relive it it, word for word, remembering every smile, every lovely feeling it gave you, over and over till the hurt is replaced with a smile ... I think I've turned into an old goo roo in my old age, but it does help me everyday ... and knowing this journey of ours is one of the hardest things in life ... so find anything you can to help you hold on to this rollercoaster we find ourselves on ... and a sense of humour is like sticking two fingers up to this cancer that wants us to brake ... all the best ... Chrissie xx

Thanks, Chrissie. 

A long time ago I discovered Meditation in a Moment on YouTube. It's calmed me down on a number of occasions. I'll try out the others you mention.
