I've raised £3000 to help fund my hip replacement in Lithuania so that I can walk down the isle on my wedding day pain free

Having been signed off AGAIN from work with finally the right diagnosis of Hip Dysplasia and mild Scoliosis, why on earth don't they stop arguing that i'm "too young" or "too fat" for a hip replacement, the amount of money and time I have spent at DR's and buying pain relief for the same thing is ridiculous!
I was born with Hip Dysplasia, had several operations to relieve the problem but not fix it and the solution is there but they just wont't do it!
Even if i only can have 2 in my life this would take me up to the age of 60 which is bloody good run for 30 years of no pain. I'm certain that this is better than another 5 years of struggling to walk, being in constant pain and discomfort and will allow me the dream of walking down the isle to marry the man of my dreams Alex without having to limp, hobble or take painkillers just to get through the day. Surely my stomach must be in pieces by now and the number of intolerances creep up by the day because of it.
Having to consider where to honeymoon will be interesting, i will have to pick somewhere i don't have to walk far or where I won't be standing for long periods of time. I may even have to make sure I can rest frequently.
I am sick of being a burden to people, I know that they will not say I was but cancelling plans last minute or not being able to do simple housework because I am in pain.
I want to volunteer for youth work but worry that one day to the next I won't be able to go because I can't sit on a hard chair or do outdoor events because of it.
If i had the £18,000 to have it done privately I would but no amount of luck is going to make that happen anytime soon!
I just feel like there is more I can do with my life if they just gave me the opportunity to do it, pain is not just your body's way of telling you something is wrong it is also cruel, unforgiving and is just the symptom to the problem. Take away the problem and it takes away the pain!
