You have just got to keep trying, keep knocking on those doors, keep making the phone calls.
The missus was in the same position as you over two years ago. She'd been out of the workforce for over ten years in the UK - she used to work at Central London 5* hotels.
Came over here with three boys over four years ago. Money was very tight so she strarted looking for work as well. She had a few interviews for reception jobs - never heard nothing back from any of them - it is just the South Australian way. As we were expecting it, she didn't let her get her down - just kept plodding on.
Dropped her CV off at a local motel and was called by the manager that night. She started the following day - there wasn't even a position advertised - the manager was of the opinion that he didn't want to lose someone of her calibre and experience. She started as a casual receptionist, was running the desk within a few months and is now management.......all from dropping her CV off!!
Keep trying mate........accept some advice from an old suit from VW.
