How much does it cost to have your ears pinned back in UK?

Im a 17 year old girl who has been bullied ever since primary school because of my ears. I can't tie my hair up because it looks ridicules. For a couple of months I've been stickying my ears back with double sided sticky tape because im trying everything to stick them back a bit but it's not working! Im not sure where to start with this. I can't afford to have this operation because I don't have any money and my parents can't afford it either so I'm not sure if I can get it free with the NHS at my age or what. Where do I start do I go to the doctors first and if yes then what the hell do I say?
