Should I do it??

I live in Australia 18yrs old, been to the UK once for soccer but got injured during a training session before any major fixtures came along. Really hated that, felt like I let everyone down including myself. Should I register myself for a football academy in the UK, I have found one that is legit, it will require me to pay $4000 aus dollars to go for a 6 week trial, everything is paid for with the fee. There has been quite a number of success stories and they are all backed up.

Should I do this? I know there is a possibility of not being selected/scouted but this is all I dream about, my whole life I have only ever wanted to play professional football, I cannot picture myself doing anything else, I eat, sleep and breathe football.

Pls help :) :/
