I have ask advice to another friends and reading the articles similar to my problem. After so many advice, I guess my current move is to build up my cv (which I'm doing right now) and applying to another job while I'm still working under their nose. Since job searching won't be easy and fast to get another boat, at the same time I would still wait for their response, but not put my hope too much like I used to. I guess, I have to face my fear again now.

Thanks for suggestion and advice. I still accept any kind of advice through. I'll update soon if I get better job offer or if they manage to response.
