Hey Bat, stay with it, it will all be worth it in the end, those that go through weight lose surgery on the NHS seem to be pulled through the hoops, its enough for you as an adult to make the decision to go through with this sort of life saving surgery in the first place, then to have to convince others that have nothing to do with your or your life that this is right for you and your life is in my opinion outragious. I think it all comes down to money, a bypass on the NHS costs about 10k in the UK, so its a significant amount of spending on one paitent, that said the specialist consultants i've seen consider this type of surgery as life saving, and therefore no different from any other type of operation that preserves life !
I chose to go private for mine and dispite the cost i'm glad i did, i dont think i could have faced a wait of up to a year !
But keep going its worth it !
