Schizoaffective is a hard road sometimes. I am probably a bit different to you in that I am in a small regional town with limited services, unlike the thriving metropolis of Sydney.
There are a number of groups available in Sydney both within the public system and privately, if you can afford it. There are so many community health centres and support groups there it is quite easy to tune into one of them. I am sure you know this.
The biggest problem I have had is knowing I have a problem and getting on top of it quickly. Getting to the E and A is usually my first line of attack when I have a major episode.
I also have given the local coppers a heads up and they will take me off to he MH clinic if needed. I also gave them some info on SchizoA which they did read, so they know a little bit about it.
I am not sure if you get the full delusions, hallucinations, psychosis, manic depression, severe mood disorders and all the jazz that goes with SchizoA but depending on that there are some strategies that can ground you so that you can cope. I am sure your mental health team has taught you these already.
As you know the symptoms of this MI can be very extreme. Even my schizophrenic flat mate is surprised by the range of behaviour that can arise from it.
My biggest tip is to know what your particular symptoms are in intricate detail and have your MH team tailor your treatment towards you specifically. I also found that the medication treatment can be quite different and it can be very difficult to arrive at the combination that works best for you, as it can be in other MIs as well..
I found it very important to not feel like a victim, but rather celebrate in a way my ability to deal with it, even if it was only partially effective.
Getting on top of it? I don't know. The big thing is to make sure it doesn't get on top of you. There is a lot of ignorance and in a way complacency about Schizoaffective Disorder and I am sure you know already it sort of gets lumped in with Schizophrenia, so its identity is somewhat blurred.
In my experience it is so different to schizophrenia, it really needs its own specialised treatment regime.
As time went on I found I got comfortable and somewhat accepting of the diagnosis and live with it in a kind of cojoint arrangement, but where I manage it rather that the other way around. Knowing it and understanding your MI and yourself and doing everything you can to keep yourself strong, safe and well is the key.
