Few years back I was stuck at the same place as You are now..
No bank would give me a loan since I had no financial security. What I have done to make money over the course of 4 years I decided to become a Cabin Attendant for one of the ME companies, it was not easy but it was very much doable. Besides money I was also part of industry that i wanted to work for, this was a great example if I could handle the life in a suitcase away from home. Meanwhile working I also made quiet a few contacts that I am grateful to to this day and forever will be.
Another suggestion would be to take a look at modular schools that are cheaper.
Now cheaper does not always mean better, but for a little over half of what Your current school cots You could get a really good training on fairly new aircraft's in not so developed countries in Europe.
Kind Regards
