Unable to find assistance after many years of trying

I've been looking for "help" for many years now but have been stuck on a loop: 

I'm considered too chronic for low level community health and all local providers, plus one external, have attempted to refer me to the hospital, private psychologists are not useful and have made it clear someone with my level of psychosocial disability requires case management which means local oversight, but despite being referred to the community health team at the local hospital in writing at least three times over the past few years, as my needs are "chronic" rather than "acute" I'm not considered eligible for their services.

In the last three months I've had the fire department called on me twice because I forget I'm cooking and set things on fire, I flooded a large room because I forgot I'd left a tap on, and in a couple weeks I have to go into hospital for a lot of dental work because I forgot to brush my teeth for a few months straight. I'm incredibly isolated but lack the ability to do anything about it, people tire me out immediately and I've been unable to really participate or enjoy hobbies for years. I'm not saying I know what I need, but I don't need a Karen giving me six to ten sessions of demanding I just go for a walk or that I need to challenge my cognitive biases.

The thing that really bothers me is the knowledge I'm not alone: I know there are other people in the community stuck in the same kind of situation. 

Recently an organisation called Neami National started up a wellness coaching service. Six free sessions with a "wellness" coach, not even a trained mental health professional. Isn't this the exact opposite of what is needed? Wasn't the commission into mental health in Victoria supposed to give me an option, any option outside of just being thrown around in a circle? I'm tired and I am getting increasingly desperate every time I have a downturn, and despite putting my hand up nobody can tell me where I'm supposed to go or what I'm supposed to be doing.
