Thanks again @Emelia8  and you too @DJMasters 

Em the application I've done has all the evidence with it that they need to decide if I'm eligible for a priority placement.  My support worker I spent an hour talking with this morning (on the phone as not able to do in person yet coz she got tested last week) has offered to do a letter for me about how I'm being affected in my current situation.  To send to housing dep't to go with what I've already given them.  Hopefully it will help more.  The sw was so supportive and understanding this morning and talked about how I don't have real choice and control in my current situation (the aim of NDIS funding overall) and even said that what my brother's been doing is almost a kind of abuse that should be reported.  That's scary stuff because if it did  happen I'd definitely be out on my ear.  She also is going to have a talk with my support coordinator about the situation.  I asked her to be sure to say that no-one is to contact bro or sil directly at this stage.  I hope it all pans out without more drama.  It's so hard to just be humble and listen to bro's stuff and respond with comitment to do more of what he wants when he's basically boot-strapping me.  And I'm feeling super defensive but have to control myself and not react.  So disempowering, that's why I'm feeling so down today.
