Mate, good legal advice would be one of the better places to start, but check out those with a good track record in that particular specialisation.
Clearly the outcome is extremely important to you, and more so from a temporal point of view given the aspect of continuity with flying training. However you should remember the legal brains you may choose to represent you, will get paid whether you win or lose, hence the caveat of getting GOOD legal advice.
As other posters have implied, you are in the top part of society with brains, apptitude and I assume youth on your side, so whilst the dream may slip from your grasp, the other opportunities for bright young men are many, varied and in certain fields - ultimately very rewarding.
If you really want to stay flying, you could consider moving to Oz and look at the RAAF, I hear F18/35's are going to need crewing.
Look forward not back, and good luck,
