Welcome @Frame 

I'm glad that you've been able to reach out here and I hope that it's a really positive first step for you. 

I hear how hard it can be to find the right support for you, particularly with the costs attached to many of them. I wonder if you'd consider telehealth psychology sessions? There are a number of services that operate as online clinics and can offer bulk-billed appointments with a mental health care plan from your gp (up to 10 sessions a year). If this interests you, a search of "bulk billed telehealth psychology clinic" should bring up a number of relevant results

Other free services that might be helpful are SANE's guided recovery program, or BlueKnot, who specialise in complex trauma, and lastly without knowing you gender this one may or may not be relevant to you - Mensline

I hope that there is something in here that is helpful to you, and again, good on you for taking this step in reaching out
