most human beings tend to end any effort regarding one's dream by saying something like "dream on..." - just because they're afraid of failure.
It is your wish and your dream. Persue it!
One time you'll look back at your life. If your dream about flying will not realize itself, maybe you'll be saddened about it. But you will have gained experiences no one else has.
If you'll look back at your life and you've never even tried there'll alway be a hole in your heart.
Talk to an FAA med, talk to the "Extender" ;-) , forget about the pain and all the advices... and DO WHAT YOUR HEART SAYS (take care and outweigh the risks you take, but follow your heart).
I wish you all the best for it!
