Hello Hannerilana, and a warm welcome to the forums.
I'm so sorry to hear from what you have told us, but I can definitely relate to complex trauma, but I've found that this may help you if you copy and paste this in your search bar Blue Knot Helpline on 1300 657 380 or firstname.lastname@example.org who can provide support for people.
Sane is also available https://www.sane.org and if you look at this site 'What hope is there for complex trauma survivors in Australia'.
Having a difficult mother and you not wanting to take medication is something we'd to talk about, plus any accommodation.
Hope to hear back from you.
