Get a book on self-hypnosis from the library or a bookshop, Broomhilda - it could be the best $5 you ever spent.
I know, easier said than done when you are staggering around banging your head off the wall and moaning with pain - your concentration for reading is not that great at present, I would bet, never mind driving anywhere.
If you have done it before, all the gradual relaxing of muscle groups and limbs one by one, regular even breathing and mental visualisation will come that much more easily - like riding a bicycle, your body never really forgets, it just needs more reminding of how to tune out the distractions. Personally, I used to find TV was the closest thing I could ever find to hypnotism without going into a trance; if you could take some old-fashioned barbiturates then you might find things even easier,
they don't call those hypnotics for nothing ! (But of course you may find there are all sorts of contra-indications against mixing those with your other medications.)
Oh dear, I've gone into that male "sort the problem" mode, haven't I ? Any minute now I will start doing long range analysis of XRays and pronouncing which herbs helped my auntie when she had toothache or how Crohn's really doesn't involve any real pain, it is all imaginary...
Well, (((hugs))) anyway. I will appreciate my day all the more for it not being yours Broomhilda, I promise you !
(Yes, I am taunting you with those teeth here.
