Student. Becoming Homeless. Next Step?

So, I'm 23 years old, and got accepted in a PhD program. I was originally going to commute from home. I had been living with my parents. Woke up this morning, got in an argument. Vomited from the stress. Got in another argument, and pretty much been told to pack my stuff and leave. I don't have any money. I'm still waiting to see if my financial aid will even support my tuition. I'm wondering if I should notify the university that I'll be homeless. Any advice?
