Welcome to bb and thank you for trusting us with your story.
I am so sorry that you didn't receive the right help in your initial time of need. The consequences of this "system" failure for you have been significant and again I am sorry. You deserved so much more.
I really feel it important to address your homelessness as a matter of priority. Do you feel strong enough to attemp this?
If so, please visit your local Salvos and talk through your situation with a representative. They should be able to offer housing assistance and they also have legal services.
I mention this because your injury occured at work, which means you can make a Work Cover claim. You may not be ready to deal with this at present but just keep it mind for when you are ready, as I'm sure any financial assistance would be welcomed. Equally you may be entitled to victims of crime compensation but you will need legal advice to make this determination.
If talking to the Salvos seems daunting, please call the bb support line on 1300 22 4636 and they will be able to help you take the next steps with regard to accessing social services and your mental health.
Life can get better but you need to approach this one step at a time. How do feel about first working to get a place to stay? Do you have any family or friends that could help you?
Kind thoughts to you
