Giving up? You haven't even started. Sorry if that may appear a bit blunt but that's the truth.
You're young enough to get a job and work for a few years and save up the cash. Working will give you a real appreciation of what you're worth and you won't be suckered into any exploitation set ups.
Consider working for an airline that has taken on their employees as flight crew, eg easyJet.
The industry is very cyclical and is extremely sensitive to the economic cycle. It looks like the hiring boom is coming to an end.
If I were you, I'd get the best paying job (or several jobs) I could find and save like crazy. Yes, you'll miss out on a new car, a fun holiday(s), big nights out with your mates, but if you really want this, that's what you'll do.
