Devyn,
Very valid points about the fear you feel about these things,,,,
I too have some trouble with them but have found that if I don’t look at the machine when I enter the room, lie down and close my eyes and NEVER open them until I am finished that I do well. I even had one done with a cloth over my eyes! It made it so much better. I also lie there and sing hymns to myself continuously,, trying to think of the next one keeps me busy,,,,
As far as the tightness of the machine,, there isn’t much to do about that except keep telling yourself that you will fit and it won’t get any tighter.
,,,, I don’t know if you are having it done at the same place as before,,, but I have found out that there are machines that have different size bores or openings! The machines at my neurosurgeon are much bigger than at my local hospital,,,, SO much nicer,,,,
Just a few tips/ tricks I use,,,, best of luck,,, of course a Valium never hurt
