@Kegsy76 i'm so sorry to hear they're not open for a few more days. please know that your financial situation is not a reflection of your worth. this is hard time, but it does not define who you are, you are capable of getting through this and you're not a failure for struggling - you're so very human.
there's a lot of financial and mental health services on this page: Mental health and financial wellbeing support | State Revenue Office (sro.vic.gov.au) - you may need to wait till the morning for some of the financial services as they are currently closed, but the mental health ones like Lifeline and SCBS are available 24/7.
you can also give these a try:
otherwise, please do reach out to someone (friend/family member, etc) and see if they can assist you in the meantime. please be kind to yourself. 💙
