Joao what you just wrote reminds me so much of what I told you 6 months or more ago, when you were looking at the possibility of going for P2F with Farnair.
Yes, you've been waiting for a break for 18 months now, yes you have a 60K bank loan, yes instructing doesn't pay well, yes you want to be on an Airbus-boeing, and YES, nobody reply's to the hundred of CVs you've sent, but it's not your FAULT, it's nothing personal. It's jst how the market is right now. Nobody get's a break in Europe, except the Ryanair/Easyjet cadets, who btw are killing it for the others.
There's not much to do but to wait, stay current, try different local companies and see if you can get a break there.
