You have nothing to lose!
True, but if your parents re-mortgage to fund training they certainly do.
I chose (5 years ago) not to even bother asking my parents to stump up the cash, it was a personal decision, but I felt they had already done more than enough for me. So I got myself 3 jobs and worked my socks off to fund my training. I made it, all the way through, no P2F nonsense and got a job not too long after finishing my training. I should point out I got the job during the downturn. Lots of networking, and LOTS of luck, I happened to be in the right place at the right time, but then again so were a few others who also got FO jobs.
PS it was all worth it, I enjoy my job more today than I did when I first started. Like a good wine it gets better with age.
