Hello and welcome to the forums @Gthan. Thanks for the tags @utopia @Bunniekins @Queenie
Utopia's advice is the best place to start I think Gthan. Asking your GP doctor to refer you for psychologist and psychiatrist. For the psychologist, if your GP does a Mental Health Care Plan for you it is valid for 12 months and entitles you to 10 psychology appointments, with a medicare refund of $125.50 for each session. A lot of psychologists won't charge you a 'gap' fee on top of that. Assuming you have a medicare card. For psychiatrist it is hard to find one who bulk bills except through the Public Health System - your GP should be aware of the options there. Private ones can be very expensive with only about 50% rebate from medicare. If you are going to apply for a Disability Pension through Centrelink you will need reports from these people to show how bad things can be for you. Same goes if you decide to apply for a National Disability Insurance Scheme (NDIS) plan and package of funding. I have a thread on here called 'Anyone Started with the NDIS?' (type it on your search bar at the top of the page for a link to it (maybe someone hear knows how to post a link in this thread for me). There is a lot of information about the process of applying for NDIS on there, but I give you a content warning as my experience so far is difficult. For this you have to prove that your disability is life-long and significant - and they don't recognise many cases of 'psychosocial' (mental health) conditions.
Hoping all this information is clear for you. Don't hesitate to ask me more questions but I will only see them if you type '@eth' in the post. I understand how overwhelming the whole matter is for you and hope to help. But do understand that in these forums we are all people with varying mental health issues helping each other with suggestions. We are not therapists.
