Roughly the same age and location as yourself and I found myself on a cadet program at one of the big schools. Not impossible to do but expect to contribute the vast majority of cash yourself either through loan or savings. Put some cash aside for living costs or, if you haven't been to university, you can apply for funding towards the course. Expect 3-20k from that method depending on your financial situation.
As others have said get a medical and perhaps a trial lesson or two, see if you REALLY want to do this because it is a slog at times (training).
Good luck.
