Thanks for your replies .

I'm pretty sure I don't really want to go back to finish the units - they are all English which I really don't enjoy. My two majors were Sociology and English, and I've finished all my Sociology units. Maybe if I had sociology units to go back to I might be a bit more motivated, lol.

A big part of my thought process is about disappointment. I feel I'll disappoint a few people, (mainly my parents) by dropping out. Growing up I was always told how smart I was, so it was just automatic for me to feel I should go to uni. I feel like my parents will say (or think) that I'm wasting all this potential, etc.
On top of that there is the thousands and thousands of dollars of debt sitting there. I feel like I should get something for it, and if I don't finish I won't. DH and I have no way of paying it off any time soon too.
I wonder also if DH might just be a bit annoyed about it. He's always so stressed about money, so having all that debt and not being able to pay it off anytime soon (especially since I probably won't be working for many years).

I'd be happiest just to be a SAHM and have lots and lots of babies, lol - but there is so much more to think about. I'd love it if a job or career jumped out at me one day where I could say "That - that is what I want to be" - but for now being a mum is all I really want.
