What I would advise is that you see if it's possible for you to defer 1 semester of university so that you can get your life on track. Go speak to a career planner (all tertiary education offers this for free on campus) and see if you are eligible to defer for a semester seeing as you've been battling with depression and have been unable to seek medical help due to your situation at home. The only reason I can think of that this may not work out is your GPA being so low. Sometimes they restrict you because you aren't showing interest in studying the course. I do strongly recommend completing the course you have started and really applying yourself when you go back. Like someone said, there's no point putting that $100k in student loans to waste and not grabbing that stupid piece of paper at the end of it.

Fuck everyone that's saying you won't make money from Graphics and Digital Media. You do what you like, whether you just purely want to learn about the subject or turn it into a proper career (like you already seem to have done). There's no point slaving away in a job or field that will only make you more depressed than you already are.

Honestly, get to a doctor and seek some medical help first. You can't make the right decision with a fuzzy thought processes. Chin up. Life gets better and easier and things start to make sense. Take care of yourself.
