You are a lucky man living in Australia. I think that you may need some company and another job perhaps.
Perhaps a mining job in WA will do the trick and you could become a driver or whatever you want to be.
Conditions for miners have vastly improved and the pay is excellent, I believe. A couple of years there will put you right and you could save quite a lot of cash.
There is a dire shortage of mining staff and earnings can be a lot more than you are getting now.
