Why follow a path where there is huge financial risk and little chance of success when you can wait a couple of years, follow the same path but with hopefully less risk and more chance of success? You're only 19 for God sake. You have Jack s**t life experience. So far you demonstrate the character of a small child who just screams until they get what they want. Difference is you're an adult and screaming won't get you a job when you've finished. I suspect that you'll believe it was the nasty mean airlines and HR personnel's fault, not your own. Go and get some real world life experience then do the training if you still want to.
At present I think you have entirely the wrong attitude. You come across as arrogant and selfish. Neither of these attributes are welcome on the flight deck. Get the class 1 medical and grow up. Please.
