Firstly, I admire your attitude (in regards to doing it yourself because you can't find opportunities).
I would say though, if acting is your dream, maybe you need to move somewhere where you can make it happen? It might involve starting as an extra, but you have to start somewhere (you might meet someone who believes in you while being an extra). I understand it is difficult being a foreigner, but it is possible (granted, probably incredibly difficult). Personally, I seek foreign actors (I hate how american films only have American characters, British films only British characters - and their foreign characters are horribly misrepresented stereotypes) - but I know I'm in the minority there.
