I'd like to join Sophie_M in welcoming you back to the Forum. I'd also like to say it has been a good couple of weeks since you posted this time and it has taken until now to get a response. Please understand it is not you, it is not the subject of your post, it is simply our system here does not always do what we want
Being left hanging would have been most discouraging to say the least.
Now, frankly I'm in awe of you. I know what happened in Tassie and it would have been bewildering and truly horrible. Then coming to Victoria and having your best efforts sabotaged and having to live firstly with a toxic and abusive family, then in a tent, all the while with your medical condition and that idiot harassing you.
However in the end you beat the lot, have a job and a place to live -amazing and wonderful. I'm under no illusions as to the problems, financial, medical and practical you still face, but to have come so far shows strenght, tenacity and ability. If you can beat all that has happened, you can beat anything.
With the idiot, now you have your own place please consider if he fronts up again getting the cops to help you get him out and ask them about getting a personal safety intervention order if needs be. I'm sure if you have contacted 1800RESPECT already they will have filled you in and hopefully listed support options to go for in your area.
You asked about getting your life back. Well, you are on the way already. You don't say much about how you feel, the thoughts you might be happening, or what your main worries are. Maybe your body, maybe finances and the ability to keep working, maybe the future in general, maybe reliving the past
I can only give you very general ideas. A GP at least, even by telehealth, to assess you physically and mentally. There may be help there. Anglicare financial advice service if money is a big problem, contacting a Cerebral Palsy society to see if there are any resources you can tap
Generally being in touch with people who are not a threat - do you have family or freinds back in Tassie to talk with ? Perhaps someone at you job? It makes a difference not feeling alone.
Most important (my physical and mental issues are different form yours, but the idea holds true) and that is to do each day something you really enjoy and takes you away from the grind of life for a little while. It need not be big or expensive, just something to look forward to.
I hope you return - the answer will be quicker
