LucindaE, PunkStar, ChaffinchofDoom, Meerka and livingzuid - thank you all SO MUCH for all your incredibly kind messages of support. Honestly, I sat here sobbing because it means so much to me.
I did make it to my appointment yesterday and took your advice: had a huge canvas bag packed with 'essentials' like carton of coconut water, ready salted crisps, every type of mint under the sun, lipbalm (to smell - lavender and orange flavour, because I didn't have any essential oils apart from tea tree and even the thought of it makes me gag at the moment), newspapers and bags (to be ill on/in), chewing gum, metoclopramide... I can't remember what else I had in there, but my dh gave me a funny look when he went to pick it up and it weighed a lot more than he thought it would(!)
Because it was a Sunday appointment, the hospital was lovely and quiet and I made sure we sat in the quietest corner with easy access to the loo (very clean, very impressed!). My midwife was incredibly kind, took her time with us and she has referred me to the hospital's mental health unit for support which I'm so glad of. The walk there and back was a bit epic (around 2 hours all in), but at least it didn't rain - small mercies, huh?! I found myself timing it in tic-tacs :-) I found sucking on ready salted crisps while there helped a bit too. The jitteriness on the way home and in the evening was something to behold. Not nice, but I survived.
It has given me a tiny bit more confidence about managing tomorrow, even though tomorrow is a much earlier appointment (12pm). My dh has arranged to be at home from 11am so we can walk up again together and slowly back again. I'll take my topped up 'sack of preparation' with me again.
It was interesting what some of you mentioned about desensitizing yourself to phobias. I hope that one positive thing that might come out of this awful experience is being at least a little bit desensitized to sickness - it's either going to be that or ending up a nervous wreck shaking in the corner and I don't really like the thought of the latter...
Well, bring on tomorrow (but not too quickly!!) and I'll try to concentrate on seeing the baby on the scan - the midwife said that apparently we can buy a picture of the scan for £2 (bargain!) if all is well.
Deep breaths and relaxation...
