Car rego and family debts

I'm writing today to ask for help with paying my car registration and also I owe a couple of people in my family a little over $8000.

I am currently 23 years old and raising my 1 year old son alone due to domestic violence, the debts to my family were from them lending me money after I left my ex partner I was 7 months pregnant and was in desperate need for money just to get me and my son all new furniture and clothes and everything else that I needed for my son when he was born as when I left I literally had just the clothes on my back. Over all my family had lent me close to $15000 and since having my son out of my forthrightly single parenting payment I have been paying over half of it per fortnight back, I have also taken out about 4 or 5 different unemployed loans just to keep paying them off but it is getting too hard, especially as my son is growing more and more every day so I need to keep buying him new clothes why still budgeting our food and rent, and now that my car has ran out of rego it has made things a lot more harder and there is no way I can afford registration along with all of the other things I am trying to pay off, for the past 3 months now I have been trying to save for registration but it just seems impossible, I have even moved pack in with my mum as I can't afford to pay rent and all of the other bills that come with renting your own place. I'm not asking for a lot but anything can help a long way. Thanks.
