I know how you feel as I myself rather be independant of the parents, but if you really want to become a commerical pilot, perhaps you will see that pride will not help in the long run.
I sourced different ways of coming up with the money but also being young meant this was a difficult task, the bank manager laughed at me when i asked what the damage would be in getting a student loan, needless to say, i had no choice but to ask the parents for help. So unless you are willing to pay the bank far greater amounts in interest for the sake of your pride, i suggest talking to the parents.
