Should i drop out of uni? What would you do?

I am a married mother of 2 young kids, (1 and 2). I have just started studying at uni. I am in my 1st week of uni and already we have had to put $500 on our credit card as my car broke down and i needed to buy text books and we didnt have enough money for food. We are already in $5000 debt, my husband works full time but barely earns enough to pay the rent, buy food and make our minimum loan repayments. We miss out on any centrelink benefit marginally. I need to put the kids in daycare 3 days a week, which i feel really bad about. I have about 2 weeks before cences date to pull out of uni without owing any fees. I feel if i dont do myh degree now, i never will. I am already 26 and feel i have left it too late already. I dont know what to do. I still need to buy more text books which we really cant afford. I have applied forscholarships but didnt recieve any. I think its all becoming too hard
