A few thoughts:
1: The NHS is amazing. The fact that I can turn up to hospital with a minor complaint and have them identify something important and then keep me there for a week while they plan a treatment -- for free -- is amazing. No-one should ever take it for granted, these places are staffed by amazing people, overworked and underpaid.
2: I'm going to have more time for hobbies but I also have to give up on any professional ambitions I had because I'm not going to be able to get a full time job until I have a transplant.
3: Everyone is treating me as though I'm dying but I feel fine to be honest.
4: The dietary restrictions for kidney patients are WEIRD. I can't have anything that's high in potassium, sodium or phosphates, so nutritious vegetables are out. Not being able to eat potatoes is heartbreaking but probably good in the long term hehe (I can eat an overboiled potato mush if I really want to but only without salt...).
I also get all the protein removed from my blood 3 times per week so I need food that's high in protein but low in mineral content, with no salt. This will take some adjusting to.
5: I now have a tube inserted into my chest, and the scar is going to be right on top of my only tattoo. Typical.
Now to attempt to negotiate the crippingly depressing UK benefits system...
