I think the music idea is really great. Something to take your mind off the anxiety is the best. I was wondering, could you break this 45 minute trip up? Can you stop somwhere,stretch your legs, have a cup of coffee (de-caff obviously!!) and clear your head. I find a tough task is easier to accomplish if I split it into bits. This may not be possible, but it's just a thought. Good luck, and have some chocolate along for the ride!!!
I alone can do this, but I cannot do it alone.
