Hello and welcome to the forum. I'm not at all scared off and would like to continue chatting to you.
You new self-awareness is commendable. So often people deny the less attractive side of their characters or find some attributes are attractive despite the harm it causes. It's great you want to change.
I suspect there is a difference between you asking for coping mechanisms and my presumption you want to change. Keeping a lid on our undesirable parts is hard work and so often leads to an explosion which can be scary. Better to find the cause and deal with that.
You said, cant afford professional help and I wont be able to get a free counselling session for 3-6 months due to waiting times. You can ask your GP for a mental health plan and see a psychologist. Your GP may know of someone who bulk bills Medicare or has minimal gap payments. The drawback is being allowed only ten sessions per year. Is that what you mean by not being able to access free counselling? If so I suggest you make an appointment to be seen ASAP and meanwhile try some other resources while you wait.
There are many organisations who offer free or very low cost counselling. Try Relationships Australia, Salvation Army, Anglicare. Also look at Headspace https://headspace.org.au/ who offer counselling and information. There is also Mindspot https://mindspot.org.au/ All these resources are available though not necessarily near you. Headspace and Mindspot are online which you can search to see what help they can provide. Very handy.
Please return and tell us how you are getting on.
